Charles H. Spurgeon on Psalms 92:4

For thou, Lord, hast made me glad through thy work. It was natural for the psalmist to sing, because he was glad, and to sing unto the Lord, because his gladness was caused by a contemplation of the divine work. If we consider either creation or providence, we shall find overflowing reasons for joy; but when we come to review the work of redemption, gladness knows no bounds, but feels that she must praise the Lord with all her might. There are times when in the contemplation of redeeming love we feel that if we did not sing we must die; silence would be as horrible to us as if we were gagged by inquisitors, or stifled by murderers. I will triumph in the works of thy hands. I cannot help it, I must and I will rejoice in the Lord, even as one who has won the victory and has divided great spoil. In the first sentence of this verse he expresses the unity of God's work, and in the second the variety of his works; in both there is reason for gladness and triumph. When God reveals his work to a man, and performs a work in his soul, he makes his heart glad most effectually, and then the natural consequence is continual praise.
