I only ask that you consider the thief on the cross next to Jesus ... to him The Lord And Savior said, "Today thou shalt be with me in Paradise." It is in God's hands regarding baptism, etc. But there is only One Way, Truth, and Life, Jesus The Christ. No man cometh unto the Father but by Him.
Yes I do believe the thief on the cross story, but there's a reason that he was going to be with Jesus that day. He believed in Him as he called him Lord. "And he said to Jesus: Lord, remember me when thou shalt come into thy kingdom."
How do we actually know that the thief was never baptized? The Scripture is silent on it. He may have been at one time before his execution or not. At the least, Baptism of blood would apply to him.
