Some are addicted to money, some to sex, some to worldly goods.
Whatever we are addicted to, we become a slave of it. It owns us.
Scripture tells us to become a slave to Christ. Let Christ be our master. In Christ, we find salvation.
Through Him, we become united to God. In essence, we become Christ. We are Christ. And we are called to serve. In service, I deliver Christ to you and you deliver Christ to me. In service, we are called to deliver Christ to the world so that the world is delivered to Christ.
