It is basically the same thing that many Protestants believe, that if you accept Jesus as your personal Lord and Savior, your sins will be forgiven and you will go to heaven (the difference being that many of these same Protestants believe that, after that point, once saved, always saved).
What we do know is that God desires all men to be saved (1 Timothy 2:4). If a person sincerely repents of any and all of his past sins, God in his mercy will save him.
It is only by God’s grace that we are saved. It’s a gift, unrelated to any good deeds we might perform.
I will appreciate your response.
