“The Apostle also prays that the Ephesian Christians may have ‘the spirit of wisdom and revelation,’ that they may come to such a knowledge of God. This is something beyond believing, beyond trusting, even beyond being sealed with the Spirit. The difference is that in the sealing with the Spirit we are given to know that we are His; the Holy Spirit ‘bears witness with our spirit that we are the children of God’ (Romans 8 :16). It is God saying to us, ‘Thou art my son, my child.’ Is there anything beyond that? Yes; to know God Himself! That is the summit, the ‘summum bonum.’ It is wonderful to know that I belong to God; it is an infinitely greater privilege and blessing to know God Himself. Such is the knowledge which the Apostle desires for these Ephesian Christians.” —D. Martyn Lloyd-Jones, God’s Ultimate Purpose, (Baker Book House, 1979) p. 347
