2 Corinthians 4: 3-4
       3But even if our Gospel (the glad tidings) also be hidden (obscured and
       covered up with a veil that hinders the knowledge of God), it is hidden
       [only] to those who are perishing and obscured [only] to those who are
       spiritually dying and veiled [only] to those who are lost.
       4For the god of this world has blinded the unbelievers' minds [that they
       should not discern the truth], preventing them from seeing the
       illuminating light of the Gospel of the glory of Christ (the Messiah), Who
       is the Image and Likeness of God.

       1 Corinthians 1: 18
       18For the story and message of the cross is sheer absurdity and folly to
       those who are perishing and on their way to perdition, but to us who are
       being saved it is the [manifestation of] the power of God.

       1 Corinthians 2: 14
       14But the natural, nonspiritual man does not accept or welcome or admit
       into his heart the gifts and teachings and revelations of the Spirit of God,
       for they are folly (meaningless nonsense) to him; and he is incapable of
       knowing them [of progressively recognizing, understanding, and
       becoming better acquainted with them] because they are spiritually
       discerned and estimated and appreciated.

The problem can be corrected, though, and the next two passages provide  references to the starting point:

       2 Corinthians 3: 16
       But whenever a person turns [in repentance] to the Lord, the veil is
       stripped off and taken away.

       John 3
       3Jesus answered him, I assure you, most solemnly I tell you, that unless
       a person is born again (anew, from above), he cannot ever see (know, be
       acquainted with, and experience) the kingdom of God.

Clearly, a spiritual re-birth is needed.

Many people believe "all roads lead to heaven," but that is not what the Bible says:

       John 14:6
       Jesus said to him, I am the Way and the Truth and the Life; no one
       comes to the Father except by (through) Me.

       Acts 4: 12
       And there is salvation in and through no one else, for there is no other
       name under heaven given among men by and in which we must be saved.

       1 Timothy 2: 5
     For there [is only] one God, and [only] one Mediator between God and
       men, the Man Christ Jesus,

The last 3 verses make it clear there is only One way to be saved, and One who can save.  Another common belief is that we can get to heaven by doing "good works," and by being "good" people.  Again, the Bible makes it clear that belief is not true.

       Ephesians 2: 8-9
       For it is by free grace (God's unmerited favor) that you are saved ([1]
       delivered from judgment and made partakers of Christ's salvation)
       through [your] faith. And this [salvation] is not of yourselves [of your
       own doing, it came not through your own striving], but it is the gift of
       God;
       Not because of works [not the fulfillment of the Law's demands], lest
       any man should boast. [It is not the result of what anyone can possibly
       do, so no one can pride himself in it or take glory to himself.]

If we could be saved by our own good works there would be no reason for Jesus to have come in the first place.  This passage, and some found below in Romans chapter 3 make it clear we are all sinners, and cannot be saved by own own good works.

       Romans 3: 10
     As it is written, None is righteous, just and truthful and upright and
       conscientious, no, not one.(3)
 
Romans 3: 20-31
       20For no person will be justified (made righteous, acquitted, and judged
       acceptable) in His sight by observing the works prescribed by the Law.
       For [the real function of] the Law is to make men recognize and be
       conscious of sin [[1] not mere perception, but an acquaintance with sin
       which works toward repentance, faith, and holy character].
       21But now the righteousness of God has been revealed independently
       and altogether apart from the Law, although actually it is attested by the
       Law and the Prophets,
       22Namely, the righteousness of God which comes by believing with
       personal trust and confident reliance on Jesus Christ (the Messiah). [And
       it is meant] for all who believe. For there is no distinction,
       23Since all have sinned and are falling short of the honor and glory [2]
       which God bestows and receives.
       24[All] are justified and made upright and in right standing with God,
       freely and gratuitously by His grace (His unmerited favor and mercy),
       through the redemption which is [provided] in Christ Jesus,
       25Whom God put forward [[3] before the eyes of all] as a mercy seat
       and propitiation by His blood [the cleansing and life-giving sacrifice of
       atonement and reconciliation, to be received] through faith. This was to
       show God's righteousness, because in His divine forbearance He had
       passed over and ignored former sins without punishment.
       26It was to demonstrate and prove at the present time ([4] in the now
       season) that He Himself is righteous and that He justifies and accepts as
       righteous him who has [true] faith in Jesus.
       27Then what becomes of [our] pride and [our] boasting? It is excluded
       (banished, ruled out entirely). On what principle? [On the principle] of
       doing good deeds? No, but on the principle of faith.
       28For we hold that a man is justified and made upright by faith
       independent of and distinctly apart from good deeds (works of the Law).
       [The observance of the Law has nothing to do with justification.]
       29Or is God merely [the God] of Jews? Is He not the God of Gentiles
       also? Yes, of Gentiles also,
       30Since it is one and the same God Who will justify the circumcised by
       faith [[5] which germinated from Abraham] and the uncircumcised
       through their [newly acquired] faith. [For it is the same trusting faith in
       both cases, a firmly relying faith in Jesus Christ].
       31Do we then by [this] faith make the Law of no effect, overthrow it or
       make it a dead letter? Certainly not! On the contrary, we confirm and
       establish and uphold the Law.

Romans 3, above, makes it clear again there is only One way, it comes by the personal expression of faith in Jesus  as a result of having 
spiritual eyes opened to that need by the Holy Spirit, and again points out
we are not saved through our own works.
  
Romans 10: 9-14 and I John 1: 8-9, below, again emphasize the personal need for confession of sin, and the asking of forgiveness of sin, which, as noted above in other passages,
 only comes from a personal relationship with Jesus and asking Him for that forgiveness of sin.

       Romans 10: 9-14
       9Because if you acknowledge and confess with your lips that Jesus is
       Lord and in your heart believe (adhere to, trust in, and rely on the truth)
       that God raised Him from the dead, you will be saved.
       10For with the heart a person believes (adheres to, trusts in, and relies
       on Christ) and so is justified (declared righteous, acceptable to God), and
       with the mouth he confesses (declares openly and speaks out freely his
       faith) and confirms [his] salvation.
       11The Scripture says, No man who believes in Him [who adheres to, relies
       on, and trusts in Him] will [ever] be put to shame or be disappointed.(1)
       12[No one] for there is no distinction between Jew and Greek. The same
       Lord is Lord over all [of us] and He generously bestows His riches upon
       all who call upon Him [in faith].
       13For everyone who calls upon the name of the Lord [invoking Him as
       Lord] will be saved.(2)
       14But how are people to call upon Him Whom they have not believed [in
       Whom they have no faith, on Whom they have no reliance]? And how are
       they to believe in Him [adhere to, trust in, and rely upon Him] of Whom
       they have never heard? And how are they to hear without a preacher?
 

       1 John 1: 8-9
       8If we say we have no sin [refusing to admit that we are sinners], we
       delude and lead ourselves astray, and the Truth [which the Gospel
       presents] is not in us [does not dwell in our hearts].
       9If we [freely] admit that we have sinned and confess our sins, He is
       faithful and just (true to His own nature and promises) and will forgive
       our sins [dismiss our lawlessness] and [continuously] cleanse us from all
       unrighteousness [everything not in conformity to His will in purpose,
       thought, and action].

Why not take this action right now, before it's too late?

Matthew 24: 36, 42, 44
 But of that [exact] day and hour no one knows, not even the angels of
               heaven, nor the Son, but only the Father. Watch therefore [give strict attention, be cautious and active], for you do not know in what kind of a day [whether a near or remote
                 one] your Lord is coming. You also must be ready therefore, for the Son of Man
                is coming at an hour when you do not expect Him.

            Matthew 25:13   
                Watch therefore [give strict attention and be cautious and active], for you know
               neither the day nor the hour when the Son of Man will come.

I Thessalonians 4:13-18
                Now also we would not have you ignorant, brethren, about those who
               fall asleep [in death], that you may not grieve [for them] as the rest do who have no hope [beyond the grave]. For since we believe that Jesus died and rose again,
                even so God will also bring with Him through Jesus those who have fallen asleep [in death].
                For this we declare to you by the Lord's [own] word, that we who are alive and remain until the coming of the Lord shall in no way precede [into His presence] or have any advantage at all over those who have previously fallen asleep [in Him in death].         
 
                For the Lord Himself will descend from heaven with a loud cry of
               summons, with the shout of an archangel, and with the blast of the trumpet of God. And those who have departed this life in Christ will rise first. Then we, the living ones
                 who remain [on the earth], shall simultaneously be caught up along
                with [the resurrected dead] in the clouds to meet the Lord in the air;
                and so always (through the eternity of the eternities) we shall be with the
               Lord! Therefore comfort and encourage one another with these words.

Revelation 21: 7-8
                He who is victorious shall inherit all these things, and I will be God to him and he shall be My son. But as for the cowards and the ignoble and the
                 contemptible and the cravenly lacking in courage and the cowardly submissive,
                and as for the unbelieving and faithless, and as for the depraved and defiled
                with abominations, and as for murderers and the lewd and adulterous
               and the practicers of magic arts and the idolaters (those who give supreme
               devotion to anyone or anything other than God) and all liars (those who knowingly convey untruth by word or deed)--[all of these shall have] their part in the lake
                 that blazes with fire and brimstone.  This is the second death.
 
Some other passages to consider........

       Galatians 5: 16-26
       16But I say, walk and live [habitually] in the [Holy] Spirit [responsive to
       and controlled and guided by the Spirit]; then you will certainly not gratify
       the cravings and desires of the flesh (of human nature without God).
       17For the desires of the flesh are opposed to the [Holy] Spirit, and the
       [desires of the] Spirit are opposed to the flesh (godless human nature);
       for these are antagonistic to each other [continually withstanding and in
       conflict with each other], so that you are not free but are prevented from
       doing what you desire to do. 18But if you are guided (led)
        by the [Holy] Spirit, you are not subject to the Law.
       
       19Now the doings (practices) of the flesh are clear (obvious): they are
       immorality, impurity, indecency, 20Idolatry, sorcery, enmity, strife, jealousy,
        anger (ill temper), selfishness, divisions (dissensions), party spirit
        (factions, sects with peculiar opinions, heresies),
       
       21Envy, drunkenness, carousing, and the like. I warn you beforehand,
       just as I did previously, that those who do such things shall not inherit
       the kingdom of God. 22But the fruit of the [Holy] Spirit
        [the work which His presence within accomplishes]
        is love, joy (gladness), peace, patience (an even temper,
       forbearance), kindness, goodness (benevolence), faithfulness,
       23Gentleness (meekness, humility), self-control (self-restraint,
       continence). Against such things there is no law [[1] that can bring a
       charge].

       24And those who belong to Christ Jesus (the Messiah) have crucified the
       flesh (the godless human nature) with its passions and appetites and
       desires.  25If we live by the [Holy] Spirit, let us also walk by the Spirit.
        [If by the Holy Spirit [2] we have our life in God, let us go forward
        [3] walking in line, our conduct controlled by the Spirit.]
       
       26Let us not become vainglorious and self-conceited, competitive and
       challenging and provoking and irritating to one another, envying and
       being jealous of one another.

       1 Corinthians 6: 9-11
       9Do you not know that the unrighteous and the wrongdoers will not
       inherit or have any share in the kingdom of God? Do not be deceived
       (misled): neither the impure and immoral, nor idolaters, nor adulterers,
       nor those who participate in homosexuality,
       10Nor cheats (swindlers and thieves), nor greedy graspers, nor
       drunkards, nor foulmouthed revilers and slanderers, nor extortioners and
       robbers will inherit or have any share in the kingdom of God.
       11And such some of you were [once]. But you were washed clean
       (purified by a complete atonement for sin and made free from the guilt of
       sin), and you were consecrated (set apart, hallowed), and you were
       justified [pronounced righteous, by trusting] in the name of the Lord
       Jesus Christ and in the [Holy] Spirit of our God.
