Contradiction with Ecclesiastes 7:20
Ecclesiastes 7:20 states there is not a just man on earth who does good and does not sin, which contradicts the claim of the speaker's holiness in Psalms 86:2.
Ecclesiastes 7:20: For [there is] not a just man upon earth, that doeth good, and sinneth not.
Contradiction with Romans 3:10
Romans 3:10 asserts that there is none righteous, no, not one, contradicting the plea of personal piety found in Psalms 86:2.
Romans 3:10: As it is written, There is none righteous, no, not one:
Contradiction with 1 John 1:8
1 John 1:8 declared that if we say we have no sin, we deceive ourselves, which contrasts with the speaker asking for preservation based on their holiness.
1 John 1:8: If we say that we have no sin, we deceive ourselves, and the truth is not in us.
Paradox #1
Psalms 86:2 expresses a plea for protection based on the speaker's devotion and faithfulness. A potential contradiction could arise if one interprets the plea as suggesting that only those who are faithful or devoted are deserving of protection, which might conflict with the broader moral teaching of unconditional love and care for all individuals, regardless of their spiritual status.
