“And 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.” (John 1:14)
Without God, being able to entirely fathom His omnipotence, omniscience, and omnipresence in our world and our lives is simply an impossible task. Without God, understanding the length and width and height and depth of His love for us, can only occur, and not even in its entirety, across a lifetime (Eph. 3:18).
We are told that without Him nothing was made that was made, so there would be nothing without God (John 1:3). If the greatness of God is put on a Richter scale, the scale would be beyond 11. The scale would be broken. And yet, Jesus became flesh and had the same skin and bones and brains as we do. Obviously, this is not a comprehensive list; however, we see in the gospels that he could experience physical pain as he did going to the cross, and he could understand the same heartbreak of loss that we do.
He dwelt among us, which in the Greek text means to do so as in a tent. I don’t know about you, but the best part about going camping is definitely not sleeping in a tent or other temporary structure. Even in that life, he had both the most he needed (a relationship with God the Father) and the least (both not having the extravagance many of us have and the willingness to give up anything he had to boot).
Becoming a man proved that God’s qualities are real and can be trusted. Becoming a man allowed the infinite God of the universe to show us that he knows us. God proved his omniscience by showing us he understands exactly where we are at. He proved his omnipotence by defeating death on the cross. With those two traits, he proved his omnipresence by knowing all and being in all. If that isn’t enough, becoming Immanuel, God with us, he fulfilled the redemptive promise that He would be the God of the Israelites and they would be his people (Exodus 6:7).
Certainly, God could have snapped his fingers and granted that understanding to himself, but becoming flesh and dwelling among us and suffering on the cross for our sake proved his power, glory and splendor. We can rely on these qualities of God, rest in awe of them, and feel completely secure by them.
