Beware of self-confident. Be rather God-confident as warns the Proverbs 3:5-6 Trust in the LORD with all thine heart; and lean not unto thine own understanding. In all thy ways acknowledge him, and he shall direct thy paths. The Apostle Paul warns here against self-conceit. Pride blinds the heart giving one a sense of delusion of having good one’s standing before God. The reality is that such a one has crossed the line, the boundary of God’s will and faces the chastisement of God!The verb “take heed” is a command for continual action. It literally means “to see”, “to perceive correctly”.
