If we are going to become more like Jesus, then we have to become less of us , which allows more of Him to shine through. Therefore, God is going to deal with our "flesh" first , in all areas where we are the most unlike Jesus. The NT speaks of "pruning", or "molding the clay", and this is in fact a lifelong process whereby God deals with us as Sons , Hebrews 12:6, and it tends to be a chalice experience. The reason most Christians dont deal well regarding God's pruning and the shaping transforming experience.... and are surprised by it, is because we live in a "Media driven-Entertainment" type of Christianity where huge TV ministries have to preach "love yourself, feel good" messages to maintain the huge crowds to pay for their Network air time. Mega Churches have become the status symbol of a Pastor's success, and to keep these running, they generally have to preach a mostly "feel good" type of amateur psychology message all the time and give a 15 second "alter call" at some point towards the end of their message so it "feels" legit. And because of this, the reality of the REAL Christian experience is not being told truthfully enough often enough from the Pulpit, and as a result a contemporary Christian will think that anything that hurts, or that they have to endure, or in general does not feel good in their life, must be the devil. However, the NT teaches that "Jesus learned obedience by the things that he suffered". And as we are being transformed into him, we are also going to sometimes find God working on us, and its not always fun and games, but it does create us to be more like Jesus.....which is the main thing with God.....and the ultimate end result of our Salvation. God is good all the time, and sometimes what is "good" for us is experienced during a process he is continuing in us that transforms us to be more like Jesus.
