You are completely bereft of any gift of how to apply exegesis to a passage. Go ahead and believe your own opinion. Genuine experienced scholars contradict you.
Ask any Roman Catholic if they are going to heaven when they die. They will tell you they hope so, and that any certainty would be prideful and presumptuous.
They speak this way because they do not believe in the efficacy of the precious blood of Jesus. They have been taught that heaven is bought not only by Jesus and (ESPECIALLY) Mary, but by a whole list of other check marks — belonging to the Roman Catholic Church, church attendance, infant baptism, “being good,” and a host of other qualifiers.
A born again blood bought believer does not say, “I hope I’m good enough to get into heaven.” But that’s what a Roman Catholic will tell you.
