Matthew 7:28

“And it came to pass, when Jesus had ended these sayings, etc.] Delivered in this, and the two foregoing chapters, concerning true happiness; the duty and usefulness of Gospel ministers; the true sense and meaning of several commandments in the law; concerning alms, prayer, and fasting; concerning the care of worldly things, rash judging, rigid censures, and reproofs; the straitness and narrowness of the way to eternal life, and the largeness and breadth of the way to destruction; concerning false prophets, and the right hearing of the word.
