Does God want to change my sinful behavior into behavior that glorifies God? You bet. However, you must be careful that you do not make behavior modification the goal of discipleship. God desires transformation in His followers.
“When morphing [transformation] happens, I don’t just do the things Jesus would have done; I find myself wanting to do them. They appeal to me. They make sense. I don’t go around just trying to do the right things; I become the right sort of person.”
People will come to your church to know more about God [in fact, this was the number one survey reason why teens come to FUEL]. People are curious how God fits into their life. They take the bits and pieces they like or pick and choose the ideas they are convinced will change their situation. However, viewing God like this is no different that believing He is a psychologist, medical antidote, or genie-in-a-bottle.
Changing the outside of a man doesn’t mean his insides are changed [cf. Matthew 23:25-26]. In other words, asking an unbeliever to be like Christ is similar to asking an alcoholic to quit drinking cold turkey. The alcoholic may go to AA, find community, and successfully quit his/her drinking addiction, but often trade addictions [i.e. begin smoking] because they are not encouraged to deal with the root issue of their addiction. Encouraging a non-follower to change attitudes and actions without the heart motivation doesn’t lead to lasting or permanent change. They will eventually fail because they do not have a relationship with Christ or true connection to the community of Christ [His church].
If we teach change before teach about Christ we are setting our disciplees up for disaster. Changing behavior to be like Christ without having a relationship with Christ can feed pride, give false assurance, and create an I-am-all-right-with-this-now attitude. Behavior on the outside might appear Christ-like, but on the inside they have a twisted and wicked heart. Whatever rules the heart will exercise inescapable influence over the person’s life and behavior. I am reminded often that God is solely after obedient hearts.
“These people come near to Me with their mouth and honor Me with their lips, but their hearts are far from Me. Their worship of Me is made up only of rules taught by men.”
Don’t piecemeal God into your life; He wants to break you so that you give Him everything. I want to encourage those I am discipling to or in Christ to stop fitting God into their plans and start fitting their life into God’s plan. I want to help them count the cost of commitment to Christ. Help facilitate change of the heart first and foremost to see God bring about transformodification [and yes, I did make the word up].
