Contradiction with James 2:24
This verse claims that a person is justified by works and not by faith only, contrasting with Romans 4:23, which emphasizes faith apart from works.
James 2:24: Ye see then how that by works a man is justified, and not by faith only.
Contradiction with Galatians 3:12
This verse states that the law is not based on faith, which contradicts Romans 4:23's emphasis on faith being credited for righteousness.
Galatians 3:12: And the law is not of faith: but, The man that doeth them shall live in them.
Contradiction with Romans 3:28
While this verse seems consistent, it can contrast by declaring a more universal principle of faith without explicitly referring to Abraham's example as in Romans 4:23.
Romans 3:28: Therefore we conclude that a man is justified by faith without the deeds of the law.
Contradiction with Matthew 7:21
This verse emphasizes doing the will of the Father for entry into the kingdom of heaven, which contrasts with Romans 4:23 emphasis on faith being accredited to righteousness rather than deeds.
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.
Contradiction with Hebrews 11:6
This verse states that without faith it is impossible to please God, which seems to align but contradicts implicitly when considering Romans 4:23 focuses not on actions but credited faith for righteousness.
Hebrews 11:6: But without faith [it is] impossible to please [him]: for he that cometh to God must believe that he is, and [that] he is a rewarder of them that diligently seek him.
