Jesus Christ knew the only way He would stop Satan is by becoming one in nature with him...He became one with the nature of Satan, so all those who had the nature of Satan can partake of the nature of God.
The new creation is created after God in righteousness and true holiness. The new man is after God, like God, godlike, complete in Jesus Christ. The new creation is just like God. May I say it like this, "You are a little god on earth running around."
God sent Jesus as an example to see if we could retain and maintain the Holy Spirit in human flesh.
Had the Holy Spirit not been with Jesus, He would have sinned
Had He (Jesus) not offered Himself through the Holy Ghost, He would not be accepted in the eyes of God the Father. Nor would He have endured the sufferings of the cross. Had He not presented Himself through the Holy Ghost, His blood would not have remained pure and spotless. And let me add this: Had the Holy Spirit not been with Jesus, He would have sinned.
What does God the Father look like? Although I've never seen Him, I believe - as with the Holy Spirit - He looks like Jesus looked on earth.
