III. On the Truth of the Incarnation
18. God’s arrival in the flesh is primarily to enable people to see the real deeds of God, to materialize the formless Spirit in the flesh, and allow people to see and touch Him. In this way, those who are made complete by Him will live Him out, they will be gained by Him, and after His heart. If God only spoke in heaven, and did not actually come on earth, then people would still be incapable of knowing God, they would only be able to preach God’s deeds using empty theory, and would not have God’s words as reality. God has come on earth primarily to act as an exemplar and a model for those who are to be gained by God; only in this way can people actually know God, and touch God, and see Him, and only then can they truly be gained by God.
