The desire for God is written in the human heart, because man is created by God and for God; and God never ceases to draw man to himself. Only in God will he find the truth and happiness he never stops searching for: The dignity of man rests above all on the fact that he is called to communion with God. This invitation to converse with God is addressed to man as soon as he comes into being. For if man exists it is because God created him through love, and through love continues to hold him in existence. He cannot live fully according to truth unless he freely acknowledges that love and entrusts himself to his creator. Catechism of the Catholic Church Chapter 1
He never stops searching for... Everyone who breathes and lives is in a quest to know the truth. We may not realize it but each one of us has desire to know our purpose. We possess a "philosophy" that makes us get up from bed every day. At times it is buried beneath the layers of junk piled on by years of looking for it in the wrong places. We are quite capable of self destruction, especially if we completely block out God from our quest. We fill the void with bodily desires, we numbed the senses through drugs and alcohol, we speed past it by being self absorbed in work, or we have constructed are own little dynamic world filled with logical precepts all based on a false notion. The desire never goes away, because God never stops seeking you. The poet Francis Thompson wrote about the Hound of Heaven who despite the miserable condition and miserable places we put ourselves, God still pursuits us, he desires our love. Take time reflect on this: we are the Creator's creation. That makes us very special. The Creator has a purpose for all His creations, we must discover this by moving towards Him. This takes effort on our part, but not on God's part. Prayer is the key to unlocking and removing those chains that keep us from God's love.
