In this sermon Likewise Said All the Disciples, in order to be born again you will have to repent of your sins.  That will require you to change some things.  It will require you to give up some of the ways you are living.  You will have to give up some of the things you are doing and are involved in.  It will require change as well as accepting his truth.  As He speaks to your heart now, you are bracing yourself, refusing to come to an altar. By doing so, you are denying him.
