Contradiction with Philippians 4:13
While 2 Corinthians 3:5 states that our sufficiency is not of ourselves, Philippians 4:13 claims we can do all things through Christ, suggesting an empowerment through self in Christ.
Philippians 4:13: I can do all things through Christ which strengtheneth me.
Contradiction with John 15:5
This verse emphasizes that without Christ we can do nothing, implying dependence on Christ, similar but contrasting to the notion of insufficient self in 2 Corinthians 3:5.
John 15:5: I am the vine, ye [are] the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. [without me: or, severed from me]
Contradiction with Jeremiah 17:5
This verse warns against trusting in man, which contrasts with 2 Corinthians 3:5’s implication that our sufficiency is from God and not of ourselves.
Jeremiah 17:5: Thus saith the LORD; Cursed [be] the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD.
