Charles H. Spurgeon on Psalms 6:8

"The voice of my weeping." Weeping hath a voice, and as music upon the water sounds farther and more harmoniously than upon the land, so prayers, joined with tears, cry louder in God's ears, and make sweeter music than when tears are absent. When Antipater had written a large letter against Alexander's mother unto Alexander, the king answered him, "One tear from my mother will wash away all her faults." So it is with God. A penitent tear is an undeniable ambassador, and never returns from the throne of grace unsatisfied. Spencer's Things New and Old.
