Yes, I am 100% sure that I will go to heaven.
1. I belong to a good church and go regularly.
Which Church Saves??
"Must I become a Protestant to be saved?"
Not at all. Don't waste your time trying to convert to Protestantism in order to be saved.
"Well then, how about becoming a Roman Catholic or a member of the Greek Orthodox Church? One of these religions could certainly save us.”
I’m afraid not.
“But you’re a Protestant—I don’t think that I understand. You don’t believe that Protestantism can save a person?”
Not at all! You can’t be saved by membership in any religion or denomination, whether Protestant or Catholic or any religion, but only through personal faith in the Lord Jesus Christ, God’s only begotten Son.
“Why do you say that? How can you be sure?”
Well, let’s read what the Bible teaches about Him: ‘There is no other name under heaven given among men, whereby we must be saved’ (Acts 4:12). And again: ‘You shall call his name Jesus: for he shall save His people from their sins’ (Matthew 1:21). Jesus Himself said, “I am the way, the truth, and the life; no man comes to the Father, but by me’” (John 14:6).
