Here are some wonderful thoughts about Christ picked from an 18th century sermon by American evangelist and theologian Jonathan Edwards.
“It is said that Christ is a river of water, because there is such a fulness in Him, so plentiful a provision for the satisfaction of the needy and longing soul.
When one is extremely thirsty, though it is not a small draught (the act of drinking) of water that will satisfy him, yet when he comes to a river, he finds a fulness, there he may drink full draughts.
Christ is like a river, in that He has a sufficiency not only for one thirsty soul, but by supplying him the fountain is not lessened; there is not the less afforded to those who come afterwards. A thirsty man does not sensibly lessen a river by quenching his thirst.
Christ is like a river in another respect. A river is continually flowing, there are fresh supplies of water coming from the fountain-head continually, so that a man may live by it, and be supplied with water all his life. So Christ is an ever-flowing fountain; He is continually supplying His people, and the fountain is not spent.
They who live upon Christ, may have fresh supplies from Him to all eternity; they may have an increase of blessedness that is new, and new still, and which never will come to an end.”
~Jonathan Edwards, 1703-1758
“O God, You are my God; earnestly I seek You; my soul thirsts for You; my flesh faints for You, as in a dry and weary land where there is no water.” Psalm 63:1 (ESV)
