In Psalm 78:1-7 the Psalmist observes that one of the crucial elements in determining a nation’s future prosperity and continuance is a clear understanding of God’s dealings with it. We are commanded to teach our children the glorious things that God has done in the past in order that they might know and declare them to their children. All this with the ultimate end that they might set their hope in God (v. 7).
You see here a glorious covenant continuity: Four generations are mentioned and involved in the continuation of covenant culture. This indicates that one of the critical factors in the preservation and promotion of Biblical faith and the blessings that accompany covenant faithfulness is a clear sight and understanding of the great works of God in the history of the nation.
