Contradiction with James 2:24
James emphasizes that a person is justified by works and not by faith only, which contrasts with the focus in Galatians 1:4 on Jesus giving himself for our sins (implying salvation through faith alone).
James 2:24: Ye see then how that by works a man is justified, and not by faith only.
Contradiction with Romans 3:28
Paul states that a man is justified by faith without the deeds of the law, which might contradict interpretations of Galatians 1:4 about the importance of repentance or works.
Romans 3:28: Therefore we conclude that a man is justified by faith without the deeds of the law.
Contradiction with Philippians 2:12
This verse urges believers to work out their own salvation with fear and trembling, which can seem contradictory to the notion in Galatians 1:4 of being delivered from this present evil world by grace alone.
Philippians 2:12: Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.
