Not surprisingly, then, our hymns come to have a precise content, a rich substance, a specific theme and thrust. Our hymns articulate more exactly that truth of God which has seized us and now sustains us. It is surely obvious now why we sing hymns, and why we shall always sing them. Objective hymns sing about God, even sing to God. Subjective hymns sing about us .
Many hymns fall in between, embodying elements of both.
Remember, objective hymns sing about God, his person, his truth, his way with us. Subjective hymns sing about us, our moods, our feelings, our aspirations, our response. Now think about this. The New Testament is of one mind that on Calvary's cross something was done for us, done on our behalf , done, ultimately, by God himself. What was done for us was done in order that something might also be done in us.
