Christ is the image of God.
Christ now stands in the place of God.
Therefore, relating to Christ is relating to God. And we know how to think of God because Christ demonstrated God’s nature to us.
In demonstrating the nature of God to us, Christ was also giving us an example to follow. We are to imitate the sacrificial love which motivated His life.
Thus we are to practice the behavior of Christ in the presence of Christ.
There can be no greater guide for our behavior in this earth than this. It covers the totality of our existence. Christ is all.
