When a man is really on the Lord's side, there will always be some evidence of it. He begins to follow the Lord. He is like blind Bartimaeus, who when cured, "followed Jesus in the way." Mark 10:5252And Jesus said unto him, Go thy way; thy faith hath made thee whole. And immediately he received his sight, and followed Jesus in the way. (Mark 10:52).
Jonathan surrendered heart and everything to David (1 Sam. 18:33Then Jonathan and David made a covenant, because he loved him as his own soul. (1 Samuel 18:3) and 4). It was a complete surrender of himself to the Deliverer.
That is what is wanted today in the case of every young person converted to Christ. I beseech you to be whole-hearted in your surrender to the Lord. Devotedness pays; half-heartedness is a profound mistake.

There are others who have too much of the world to really enjoy Christ. This class is to be studiously avoided. They are no use in the Church, and get no respect from the world.
