Christianity is not merely or mainly about correcting your bad habits, but about satisfying and fulfilling you in the deepest way possible, and therefore making God look as great as he is. Our hearts were designed to enjoy a full and forever happiness. However we are prone to settle for pitiful, temporary pleasures. Sin is an inadequate substitution for the wonder, beauty, and affection of God. In comparison to Christ, sin is a killjoy. It will rob you not ravish you. It will numb you, not heal you. It will slaughter you, not save you. We must trust that the God who formed our hearts knows how to fill them.
