1Co 16:14 "Let all that you do be done in love."

"Personal intercourse with Jesus is pre-eminently a cause of love, and it so infallibly quickens the affections that it is impossible to live in the society of Jesus without loving Him. Nearness of life towards the Lamb will necessarily involve greatness of love to Him. As nearness to the sun increases the temperature of the various planets, so close communion with Jesus raises the heat of the affections towards Him." C. H. Spurgeon
