To know the hymns we have to know some of the crucial points of the contents of the hymns. First, we must know some of the hymns on the blessing and experience of the Triune God. The word blessing is used here not to refer to the good things the Triune God has given us but to the praise, the blessing, we offer to Him. An example of a good hymn on the blessing of the Triune God is #7—"Glory, glory, to the Father!"—and an example of a good hymn on the experience of the Triune God is #608—"What mystery, the Father, Son, and Spirit." We also need to know hymns in the categories of the praise of the Father and the praise of the Lord.
