5. The Two Incarnations Complete the Significance of the Incarnation.
Relevant Words of God:
The significance of incarnation is that an ordinary, normal man performs the work of God Himself; that is, that God performs His divine work in humanity and thereby vanquishes Satan. Incarnation means that God’s Spirit becomes a flesh, that is, God becomes flesh; the work that He does in the flesh is the work of the Spirit, which is realized in the flesh, expressed by the flesh. No one except God’s flesh can fulfill the ministry of the incarnate God; that is, only God’s incarnate flesh, this normal humanity—and no one else—can express the divine work. If, during His first coming, God had not had the normal humanity before the age of twenty-nine—if as soon as He was born He could work miracles, if as soon as He learned to speak He could speak the language of heaven, if the moment He first set foot upon the earth He could apprehend all worldly matters, discern every person’s thoughts and intentions—then He could not have been called a normal man, and His flesh could not have been called human flesh. If this had been the case with Christ, then the meaning and the essence of God’s incarnation would have been lost. That He possessed normal humanity proves that He was God incarnated in the flesh; the fact that He underwent a normal human growth process further demonstrates that He was a normal flesh; and moreover, His work is sufficient proof that He was God’s Word, God’s Spirit, becoming flesh. God becomes flesh because of the needs of the work; in other words, this stage of work needs to be done in the flesh, done in normal humanity. This is the prerequisite for “the Word becoming flesh,” for “the Word appearing in the flesh,” and is the true story behind God’s two incarnations.
