Once you choose a master as we discussed before, you must then walk away from the old master, let it go, repent.
Peter said to the crowd, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.” Acts 2:38
To serve the new Master, you have to leave the other one; to work for McDonald’s, you have to put in your notice and leave Wendy’s. This repentance is like someone who wakes up from an affair and says, “I have got to get out of this affair because I cannot please two women. One is going to leave me. I am going to choose my wife before I end up having two women rob me of a marriage, my children, and my finances,” and they get up and they go home to stay… forever. You have to say goodbye forever to that way of living, that selfish love. Overeating or tobacco or alcohol or any vice is no different. You either obey the voice of one or you obey the voice of the other. You cannot please both the food and God. And what is more, the passage brings out the point that you will hate the one and love the other. You yourself have to get out of these affairs before you are loving the wrong one. Go home to your wife; go home to God. The wrong slave master will be the death of you. That is why the children of God had to get out of Egypt.
