Without conversion of heart we cannot serve God on earth. We have naturally neither faith, nor fear, nor love, toward God and His Son Jesus Christ. We have no delight in His Word. We take no pleasure in prayer or communion with Him. We have no enjoyment in His ordinances, His house, His people, or His day. We may have a form of Christianity, and keep up a round of ceremonies and religious performances. But without conversion we have no more heart in our religion than a brick or a stone. Can a dead corpse serve God? We know it cannot. Well, without conversion we are dead toward God.J.C. Ryle in Do You Think You Are Converted?, p. 7.
