6:1-4 The great duty of children is, to obey their parents. That obedience includes inward reverence, as well as outward acts, and in every age prosperity has attended those distinguished for obedience to parents. The duty of parents. Be not impatient; use no unreasonable severities. Deal prudently and wisely with children; convince their judgements and work upon their reason. Bring them up well; under proper and compassionate correction; and in the knowledge of the duty God requires. Often is this duty neglected, even among professors of the gospel. Many set their children against religion; but this does not excuse the children's disobedience, though it may be awfully occasion it. God alone can change the heart, yet he gives his blessing to the good lessons and examples of parents, and answers their prayers. But those, whose chief anxiety is that their children should be rich and accomplished, whatever becomes of their souls, must not look for the blessing of God.

3. long on the earth—In Ex 20:12, "long upon the land which the Lord thy God giveth thee," which Paul adapts to Gospel times, by taking away the local and limited reference peculiar to the Jews in Canaan. The godly are equally blessed in every land, as the Jews were in the land which God gave them. This promise is always fulfilled, either literally, or by the substitution of a higher blessing, namely, one spiritual and eternal (Job 5:26; Pr 10:27). The substance and essence of the law are eternally in force: its accidents alone (applying to Israel of old) are abolished (Ro 6:15).
