I'm a Christian but I thought what Graham said was ill-chosen. Not all who believe in God believe in Jesus Christ. Why say things that can only serve to divide?
Did you ever read the part in Revelations where it says EVERY knee will bow, and EVERY tongue confess that Jesus is Lord?
Today, or later; it matters not when; they WILL believe in Jesus.
Will you be with the sheep, or with the goats?
