We have seen who Jesus is by revelation of the Holy Spirit. He is the very Bread of God come down from Heaven and is as necessary to our inward man as natural food is to our outward man. That is so often proved by our choices. If, on the one hand, there is an opportunity for some spiritual food, and on the other hand there is an opportunity or invitation for some natural enjoyment, the true disciple always says: 'I am for the spiritual food! That is more important to me than all natural pleasures.' This is the kind of disciple that Jesus must have: those to whom He is the only life. That is gathered into this word which He used: 'Except'... 'Except ye eat the flesh of the Son of man... Except ye drink His blood ye have not life.' There are no alternatives to this. There is nothing that you can put into the place of this. It is this, or nothing - or, it is this or spiritual death.
Yes, He wants disciples to whom He is the only life, not just life and something else. There are whole multitudes of disciples who want Christ and something else, to whom Christ is not all-sufficient, the only life, and the Lord is going to sift out those in his body who carry the name of 'disciples'. He has always done it. He did it in New Testament times. The mighty persecutions which came upon the early Church were His means of sifting out, and through the ages He has done this thing by many means. He is doing it in the world today. Oh, what a tremendous sifting is going on amongst Christians! It is already beginning in the east and is going to develop in the west - the western world is not going to escape this. The great multitudes who may call themselves by the name of Christ's disciples are going to be found out. Let us be quite clear and certain on this point. If Christ is not our only life we are going out, for sooner or later we shall not be able to stand up to the test.
