The clear reason why we accept God’s rein in our lives is because God has done and is doing for us what no one or system can do for us. It is the power of God in our lives and this world that constraint us to serve Him. Someone would say why would you accept a government that has rules that are higher that the heavens and our answer is, Him who we serve has done for us what no drugs, philosophy, or preferential treatment can ever do for us. The power of God is truly demonstrated in the conversion of sinners from selfish to selfless. The changed life from sinner to saint is worth all that we sacrifice in this life, especially when we think of those sacrifices that we made, we were simply giving up evil in our lives. 

Romans1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
