Meat for the Masters Use

In John 17:17- 21 Jesus is praying for the disciples and all believers before he ascends to the Father and in this passage we see the key to putting ourselves in a position to be used by God in an awesome way. First He prays sanctify them which means a cleansing from the sin nature and a separating from the world and then we can become one in Him that the world may see him in us. Its then that we are truly"Meat for the Masters use".
