Proverbs 3:5: Trust in the LORD with all thine heart; and lean not unto thine own understanding.
Contradiction with Matthew 7:1

Matthew 7:1: Judge not, that ye be not judged.
Contradiction with Romans 14:4

Romans 14:4: Who art thou that judgest another man's servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand.
