Again delving too far into the religious side of the argument, but as one who believes God chooses people first, I don’t find any conversions tricky, because my job is to tell people what I believe the Bible teaches about salvation, and if God has chosen them they will be saved.
Further, I just don’t see where even a belief that Jesus is God is necessary for salvation. He obviously is God. But if you believe in Jesus (and he was a man), and you believe God raised him from the dead, and you confess Jesus as Lord, it seems you could be saved, even if you don’t know yet that Jesus was God, part of a Trinity, or existed from the foundation of the world.
I’m not trying to argue for a permissive gospel, or to doubt the Godhood of Jesus. I’m just saying that I am not ready to claim a requirement on a person that I don’t clearly see spelled out in the Bible.
Let's cut to the chase:
John 6:28-30
28. Then they asked him, "What must we do to do the works God requires?"
29. Jesus answered, "The work of God is this: to believe in the one he has sent."
