John 1:14, “…the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.“
God’s beauty is revealed in Christ’s incarnation, in fact there are three ways that come to mind:
1) Christ is the exact image of God (Heb. 1:3) and reveals God’s glory. Not only does Christ come into this world as an image bearer, but He does so glorifying the Father in every way. Therefore, Christ’s humanity does not conceal God’s glory, but is seen and experienced through faith. Something we should be able to testify of.
2) God’s beauty is revealed in Christ who took the form of a servant (Phi. 2:5-11). His beauty is seen in His humiliation and exaltation. His humiliation in death, and His exaltation in the resurrection & coming reign. But without the first, the latter would not come. The cross had to happen for exaltation to occur.
3) Lastly, The transfiguration of Christ is a glimpse into His exalted glory. The divine act where we read of His glory piercing through His flesh, should have us in awe, as the veil is pulled back only as a preview of the glory we will one day behold.
