Charles H. Spurgeon on Psalms 119:54

Songs in the house of my pilgrimage. See how the Lord in his wise dispensation attempers himself to our infirmities. Our life is subject to many changes, and God by his word hath provided for us also many instructions and remedies. Every cross hath its own remedy, and every state of life its own instruction. Sometimes our grief is so great that we cannot sing; then let us pray: sometimes our deliverance so joyful that we must break out in thanksgiving; then let us sing. "If any man among you be afflicted, let him pray; if he be merry, let him sing." Prayers for every cross, and psalms for every deliverance, hath God by his own Spirit penned for us; so that now we are more than inexcusable if we fail in this duty. William Cowper.
