Just as Christ entered the world becoming our High Priest, we are to see ourselves as preparing for the priesthood of the believer's. We need to learn to talk to God for man, just as Jesus spoke for us in John 17 we are to talk for one another as in 1 John 5:10-18.We have to know and understand the word of God, so that we intercede according to His will, learning not trying to go beyond it.
