Living in the now to me seems what occurs as we are "hidden in Christ", He remembers our transgressions no more, everything is now and forward. We are not giving thought to what we were, where we were, it is past. As we walk with Him we must keep up and move forward. Curry Blake spoke of Dr. Lester Sumrall once was leaving the church, shaking hands, greeting people, he noticed he did not have his Bible, he asked a member close to him, "where's my bible?", he replied it was at the podium, "go get it" he asked. Dr. Sumrall was never one to think himself more highly than another, that he should be served by others, it was asked why he had the other man go get it, "because I don't back up!" In his mind that would have been 'backing up" , or retracing his steps, he was committed to moving forward in his walk and service to our Lord.
