Contradiction with Romans 3:23
This verse suggests that all humans sin, implying that not all commandments (or statutes) mentioned in Psalms 119:86 are perfectly adhered to by people.
Romans 3:23: For all have sinned, and come short of the glory of God;
Contradiction with 1 John 1:8
This verse indicates that claiming to be without sin is self-deceptive, contradicting the perception that all God's commandments are completely followed, as implied in Psalms 119:86.
1 John 1:8: If we say that we have no sin, we deceive ourselves, and the truth is not in us.
Contradiction with Ecclesiastes 7:20
This verse asserts that there is not a just man on earth who does good and does not sin, which contrasts with the notion in Psalms 119:86 that God's commandments are always just.
Ecclesiastes 7:20: For [there is] not a just man upon earth, that doeth good, and sinneth not.
Contradiction with Isaiah 64:6
This verse states that all our righteousnesses are like filthy rags, suggesting that human adherence to commandments is flawed, which may contradict the perfection and faithfulness emphasized in Psalms 119:86.
Isaiah 64:6: But we are all as an unclean [thing], and all our righteousnesses [are] as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away.
Contradiction with Galatians 2:16
This verse states that a person is not justified by the works of the law, which could seem to contradict the implication in Psalms 119:86 of the law's absolute rectitude and role in righteousness.
Galatians 2:16: Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
