Psalm 78:4, 7 We will not hide them from their children, shewing to the generation to come the praises of the Lord, and his strength, and his wonderful works that he hath done….That they might set, their hope in God, and not forget the works of God, but keep his commandments.
The response of God’s people to the words and works of God (to Law and Gospel) is to “tell everyone what He has done,” and to make sure that succeeding generations hear and know the praises, strength, and works of God. The result will be that they will set their hope in God, remember His wonderful works, and desire to do His will.
For this purpose the Christian Church has established worship services, schools, and classes to show the works of God. Those who are taught will then hope in God, not forget, and keep His commandments. We may never see in this lifetime how important and vital is the work of the church, but one day we will see and rejoice.
