Though the fig tree may not blossom, nor fruit be on the vines; though the labor of the olive may fail, and the fields yield no food; though the flock may be cut off from the fold, and there be no herd in the stalls—Yet I will rejoice in the LORD, I will joy in the God of my salvation. – Habakkuk 3:17-18

Any man can sing in the day. When the cup is full, man draws inspiration from it; when wealth rolls in abundance around him, any man can sing to the praise of a God who gives a plenteous harvest, or sends home a loaded argosy. It is easy enough for an aeolian harp to whisper music when the winds blow; the difficulty is for music to come when no wind bloweth…Let all things go as I please-I will weave songs, weave them wherever I go, with the flowers that grow upon my path; but put me in a desert, where no flowers are, and wherewith shall I weave a chorus of praise to God? How shall I make a crown for Him? Let this voice be free, and this body be full of health, and I can sing God’s praise; but stop this tongue, lay me upon the bed of languishing, and it is not so easy to sing from the bed, and chant high praises in the fires…It is not in man’s power to sing, when all is adverse. It is not natural to sing in trouble-“Bless the Lord, O my soul, and all that is within me bless His holy name:” for that is a daylight song. But it was a divine song which Habakkuk sang, when in the night he said-“Though the fig-tree shall not blossom,” and so on, “yet will I trust in the Lord, and stay myself in the God of Jacob.” Songs in the night come only from God; they are not in the power of man.~ C.H.
