He was in the world, and the world was made through him, yet the world did not know him. (John 1:10, ESV)Nearly every statement from this first chapter of the Gospel according to John is absolutely astounding... He... the He that created the world, was in the world.
...and yet this world did not know him.
We should have. We should have known Him. We should have recognized Him. But we did not. And we do not (still).
By the grace of God alone, some recognize Him.
