How do we know Jesus is God manifest in the flesh?

In the biblical narrative, particularly in the Gospel accounts, Christ's dual nature as both God and man is established. John 1:14 articulates this when it states, 'the Word became flesh and dwelt among us.' His physical appearance, as noted in Isaiah 53, did not warrant earthly admiration, yet this obscuration did not diminish His divine essence. He is both the anointed one who fulfills the law, represented by Moses, and the prophetic tradition symbolized by Elijah. Therefore, the Gospel is steeped in the explicit declaration of His glory as God in the flesh, a truth central to the Reformed understanding of Christ's salvific work.
