Christ taught St. dismas that he, Dismas, will be back to the state of his original parents prior to the fall. That would be instantly understandable to anyone in 1c Palestine; but apparently it takes a 21c you, infected with modernist trash-thought about the Bible, much longer.
My "modernist trash" doesn't mean your "revisionist trash" is correct. Your whole argument is based on a legend concocted by the Church centuries after the fact, and on the faulty presumption that a 1st century Greek thief in Palestine would have known something about the Torah.
Your argument also dismisses the obvious flaw, namely that the Jesus' statement on the cross does not follow the thief's petition. Your argument ignores the fact that heaven is not mentioned, or that paradise is not heaven. Your argument ignores the fact that no matter how the Church tried to convolute this story Jesus' kingdom is not paradise, unless Jesus' name is Hades. Your argument ignores the fact that Jesus' promise was not kept according to the what the Church teaches. Your argument ignores the fact that the concept of Paradise as the Garden of Eden was not the belief of the Jews or the Early Christians, although the Hebrew word for "garden" (any garden) is a derivative of the Persian word otherwise known as paradise.
