Thank you for your opinion, but it really does not comport with fact. Grace, faith, works, belief, being born from above, and baptism are among a few of the many ways mentioned in Scripture. The opportunities and circumstances of each comprise an ever changing plan for Salvation unique to each of us. The notion that all one has to do is say the magic incantation to secure Salvation and to gain forgiveness of all sins, past, present and future, is itself the sin of presumption against hope.
Peace be with you
Jesus answered, The work of God is this: to believe in the one he has sent.
1 John 3:21-24
Dear friends, if our hearts do not condemn us, we have confidence before God and receive from him anything we ask, because we keep his commands and do what pleases him. And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us. The one who keeps Gods commands lives in him, and he in them. And this is how we know that he lives in us: We know it by the Spirit he gave us.
