Psalm 63:1 (NLT)
1 O God, you are my God; I earnestly search for you. My soul thirsts for you; my whole body longs for you in this parched and weary land where there is no water.

God's lovingkindness is in itself, and in the account of all the saints, better than life. It is our spiritual life, and that is better than temporal life, Ps. 30:5. It is better, a thousand times, to die in God's favour than to live under his wrath. David in the wilderness finds, by comfortable experience, that God's lovingkindness is better than life; and therefore (says he) my lips shall praise thee. [Matthew Henry Commentary]

"I don't believe in God, but I miss him."

This is the opening line from a book titled Nothing to Be Afraid Of by the award-winning British writer, Julian Barnes. Barnes, who describes himself as an agnostic, writes, "I was never baptized, never sent to Sunday school. I have never been to a normal church service in my life." And yet this agnostic intellectual still feels haunted by the beauty of Christian art and music and by what he calls the "wake up call to morality."

Our soul thirsts for God and longs to be with Him. Even the author above who claims to be agnostic feels God tugging at his heart.
