John 3:13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
Some say Christ never claimed to be God. Right here He says it and I wonder if it went over their heads like it did for me for many years. He is stating His omnipresence. If He came down from Heaven and is yet in Heaven that is omnipresence and only God has that.
He did not even make a big deal over it. He just stated it as the fact that it is and moved on. Truth is truth and God does not always get flashy with it. We need to keep that in mind when we do not see what we think God should be doing in our lives. Truth does not need anything to prop it up. It stands on its own.
