Unfortunately, you are missing the point. It is as we walk in the Spirit that the Holy Spirit guides or leads us in all truth. And this is the very essence of Christ in me. But there is a very distinct empowerment that is divine. Too many Christians have a form of godliness, but deny its power. Trying to copy Jesus in your own strength is denying that power.
Copying Jesus only vs having the Holy Spirit inside of you are two different things. In order for you to follow the law you need the Holy Spirit in you. This is what was spoken of in the Old Testament and fulfilled in the New Testament.
1 Cor 3:16 Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?
