When you say you believe that Jesus is Lord of your life. It is then you will treat others, in a way that you would want to be treated. If you are letting the devil rule your life and there is no faith and action in what you believe. Then you will treat others in the same selfish way the devil treats others. Only caring about himself and could careless about what anyone else thinks.
When you take your body, which is the temple, that you ask Jesus to live in. And let the devil use the temple that is God’s, you become very selfish and the only things you care about, are serving your needs. When Jesus comes in, you will not care about Him, or anyone else, and if you do not take anyones else’s cares over your own, then you will not recongnize Jesus.
