act 7:56

"'Look,' he said, 'I see heaven open and the Son of Man standing at the right hand of God.'"

-Acts 7:56

Towzer once said, "Self is the opaque veil that hides the face of God from us. It can be removed only in spiritual experience, never by mere instruction." I believe this to be truth, and i believe Stephen believed this to be truth. So i don't think Stephen wanted them to look up and see what he saw, but instead he wanted to share with them, what God did for him. He was trying to witness to them one last time, he was simply sharing his testimony with them. He says, "Look, I see…" He was showing them what God has done in his life, because He has been faithful to God. "Whoever defends himself will have himself for his defense, and he will have no other. But let him come defenseless before the Lord and he will have for his defender no less than God Himself." (Another quote from Towzer). This explains Stephen's Stoning so well, he did what God told him to do, and now was the test, so instead of running or trying to get out of it, he just says plain and simple, "hey, you guys know what your about to do to me, i know, God knows, but i'm still here because my Father in Heaven is here with me." "Be strong and courageous. do not be terrified; do not be discouraged, for the Lord your God will be with you wherever you go." (Joshua 1:9b). 

I want to keep my eyes on my Savior in Heaven, I want to stand boldly before those who hate me knowing the Godhead is with me, and i want to be able to tell my testimony one last time before i go, so that God can use that for those who witnessed what happened, so they can know Him.
