Contradiction with James 2:24
This verse emphasizes that a person is justified by works and not by faith only, which contradicts 1 Corinthians 15:2 where salvation is presented as being contingent upon faith and adherence to the gospel.
James 2:24: Ye see then how that by works a man is justified, and not by faith only.
Contradiction with Romans 11:6
This verse indicates that salvation is by grace and not by works, whereas 1 Corinthians 15:2 implies continuity in faith matters in being saved.
Romans 11:6: And if by grace, then [is it] no more of works: otherwise grace is no more grace. But if [it be] of works, then is it no more grace: otherwise work is no more work.
Contradiction with Hebrews 10:26
This verse suggests that deliberate sin after knowing the truth leaves no sacrifice for sins, which seems contradictory to the implication in 1 Corinthians 15:2 that holding firmly to the gospel ensures salvation.
Hebrews 10:26: For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
Contradiction with Galatians 5:4
This verse warns against falling from grace by seeking to be justified by the law, which appears to contradict 1 Corinthians 15:2 that implies steadfastness in faith is required for being saved.
Galatians 5:4: Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
Contradiction with Matthew 7:21
This verse states not everyone who calls on Jesus will enter the kingdom of heaven, but only those who do the will of the Father, contrasting with 1 Corinthians 15:2 that highlights faith and receiving the gospel as saving factors.
Matthew 7:21: Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
