Thorondir,
"An adult who goes to be baptized into the body of Christ must certainly be asking Jesus into his heart."
NOT Necessarily.
And why may I ask...is your tone so Biting and Nasty to...Chewbacca?
Chewbacca is stating the Truth, one must be Born Again before Baptism....READ What Yeshua/Jesus The Messiah/Christ had to say about this issue in the Gospel According to John chapter 3.
Jesus is speaking directly to Nicodemus and to ALL of us as well!
So...before you go on the attack...be prepared with knowing the Truth.
And Please read for Yourself (the entire chapter) John chapter 3 before You answer me.
Thank You and GOD Bless.
