Saul may be the one blinded but Ananias is the one who wants to make sure God sees clearly. "Here, I am Lord" is followed quickly by a just in case you don't know "Lord, I've heard of this man…" According to Luke's tale all Ananias needs is a little more information to call Saul brother but I image he had an exit strategy when he headed down Straight Street in Damascus. Even so his only scene in the Gospel is a story of faith that makes Paul's story possible as his baptizing "Saul, Saul, why do you persecute me" means Paul can suffer for "the sake of the name" which in turn makes the name of Jesus known. Ananias could have said send someone else but he didn't and his act of obedience opened the eyes of Paul and the eyes of countless generations who would read Paul's letters. Maybe God seeing clearly is how we receive our sight. Here I am Lord.
