For He has satisfied the thirsty soul, And the hungry soul He has filled with what is good.
-Psalm 107:9
No thirst, no satisfaction; no hunger, no fullness. Thirst proves the existence of water, and hunger the reality of food, for if water and bread did not exist, we would not desire them. The need for God evident in humanity from the beginning of time is proof of God’s existence.
A whole branch of science has emerged, studying the way the brain is “hardwired for God.” Our need for God is real, and so is He, otherwise we would not yearn for Him. And those who seek Him will be satisfied.
