Our bodies (and spirits) are also thirsty for God. The Psalmist says, "My soul thirsts for you, my body longs for you, in a dry and weary land where there is no water." Another translation has it as, "My body pines for you like a dry, weary land without water." (Ps. 63:1)
Are you thirsty? God is the bottomless well from which we can drink our fill whenever we want. Prayer is the way to access the water in that well. Drink often. Drink deeply. There is always more.
