I have responded biblically to your comments on the thief and the new covenant and have shown biblically the rationale that says the thief WAS under the New Covenant.
John the Baptist was the last prophet of the Old Covenant.
Jesus the Christ was the first preacher of the New Covenant. His own words during his ministry to a non-believing Nicodemus (early in the Book of John) were "For God so loved the world that He gave His only begotten Son that whosoever believeth in Him should not perish but have everlasting life."
This message was given to Nicodemus well BEFORE Jesus' death, burial, and resurrection. Jesus was the Lamb who was slain from the foundation of the world.
New Covenant; Old Covenant.
Just how many ways are there to have one's sin washed away and is this like the many gospels that some think the Bible teaches?
