Contradiction with Proverbs 3:5
Contradicts the idea of determination and self-reliant decision as it advises to trust in the Lord rather than one's own understanding.
Proverbs 3:5: Trust in the LORD with all thine heart; and lean not unto thine own understanding.
Contradiction with James 4:15
Contradicts by suggesting all plans should be contingent on the Lord's will, whereas Ruth 1:18 shows determination without mention of divine will.
James 4:15: For that ye [ought] to say, If the Lord will, we shall live, and do this, or that.
