Truth is one can never be like someone he/she knows very little about.Relationship is the key word here. Relationship grows as u spend time with someone. For one to be like Jesus,one has to spend a lot of time with him. This means,to have a mind like Jesus, one needs to spend good time with the same Jesus. Characteristcs of the one you spend time with will in-turn begin to show in You. In the end, they will serve and not want to be served.
