Here is one example:-
Mark 3
28 “Assuredly, I say to you, ALL SINS WILL BE FORGIVEN THE SONS OF MEN, AND WHATEVER BLASPHEMIES THEY MAY UTTER; 29 but he who blasphemes against the Holy Spirit never has forgiveness, but is subject to eternal condemnation”— 30 because they said, “He has an unclean spirit.”
Matthew 12
31 “Therefore I say to you, EVERY SIN AND BLASPHEMY WILL BE FORGIVEN MEN, but the blasphemy against the Spirit will not be forgiven men. 32 Anyone who speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age or in the age to come.
Matthew 25
41 “Then He will also say to those on the left hand, ‘DEPART FROM ME, YOU CURSED, INTO THE EVERLASTING FIRE PREPARED FOR THE DEVIL AND HIS ANGELS: 42 for I was hungry and you gave Me no food; I was thirsty and you gave Me no drink; 43 I was a stranger and you did not take Me in, naked and you did not clothe Me, sick and in prison and you did not visit Me.’
44 “Then they also will answer Him, saying, ‘Lord, when did we see You hungry or thirsty or a stranger or naked or sick or in prison, and did not minister to You?’
45 Then He will answer them, saying, ‘Assuredly, I say to you, inasmuch as you did not do it to one of the least of these, you did not do it to Me.’ 46 And these will go away into everlasting punishment, but the righteous into eternal life.”
Mark 3 and Matthew 12 has claimed that “all sins and blasphemies will be forgiven, except for blasphemy of the Holy Spirit”.
They are conditional statements, which are only true in the absence of the Exemption Clause concerning “Blasphemy of the Holy Spirit”.
Thus, Blasphemy of the Holy Spirit is the only “eternal” and “unforgivable” sin according to Mark 3 and Matthew 12.
Nevertheless, God's pronouncement of “Everlasting hell” in Matthew 25:41 is equivalent to the “eternal” and “unforgivable” sin in Mark 3 and Matthew 12, because those who are condemned cannot be redeemed once God has made such a pronouncement.
However, Matthew 25vv42–43 provides a few examples of transgressions which are not Blasphemy of the Holy Spirit, but they still carry the same penalty of “Everlasting torment in hell” simply because God has made his pronouncement of “Everlasting hell” to those who are condemned.
But if Mark 3 and Matthew 12 are conditional statements which only allows for Blasphemy of the Holy Spirit then there is clearly no room for God's pronouncement of “Everlasting hell” in the context of Matthew 25v41.
That is just one example of an apparent contradiction, which can be easily understood and resolved by arguing that the Bible is not accurately written to include Matthew 25v41 in the Exemption Clause of Mark 3 and Matthew 12.
The problem of supposed contradiction is easily understood and resolved by positing that Mark 3 and Matthew 12 are not accurately written to include Matthew 25v41 in the Exemption Clause.
Obviously, it is only one example of an apparent contradiction within the Bible, but there are several more examples that I could provide.
