Dr Lloyd-Jones on Assurance and the Baptism of the Holy Spirit

"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! It is wonderful to know that I belond to God, it is an infinately greater privilidge and blessing to know God Himself".
