Charles H. Spurgeon on Psalms 14:7

"O that salvation," etc. Like as when we be in quiet, we do pray either nothing at all, or very coldly unto God; so in adversity and trouble, our spirit is stirred up and enkindled to prayer, whereof we do find examples everywhere in the Psalms of David; so that affliction is as it were the sauce of prayer, as hunger is unto meat. Truly their prayer is usually unsavoury who are without afflictions, and many of them do not pray truly, but do rather counterfeit a prayer, or pray for custom. Wolfgang Musculus, 1497-1563.
