Charles H. Spurgeon on Psalms 119:37

Quicken thou me. Another quickening ordinance is prayer. How often doth David pray for quickening grace? five or six times in one Psalm. He begins many a prayer with a heavy heart, and before he hath done he is full of life. Therefore, pray much, because all life is from God, and he quickens whom he will. Only let me add this caution, before I let this pass, Be sure thy understanding and affection go along together in every ordinance, and in every part of the ordinance, as thou wouldst have it a quickening ordinance. Matthew Lawrence, in "The Use and Practice of Faith, "1657.
