Contradiction with James 1:17
While Psalms 9:1 emphasizes giving thanks and praise to God, James 1:17 suggests that every good gift and perfect gift is from above, which might imply focusing on the gifts themselves rather than strictly on the act of giving thanks.
James 1:17: Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.
Contradiction with Philippians 4:6
Psalms 9:1 encourages giving thanks with a whole heart, while Philippians 4:6 promotes making requests with thanksgiving, suggesting a more balanced approach between thanksgiving and petitions.
Philippians 4:6: Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
