You're understanding falls far short.

Jesus saves us from the final end destruction, and helps us who believe on him through our daily lives. Some people get along fine without religion. What happens to them when the final destruction (from God, not man) gets here depends on whether these people continue to do it all on their own and choose to not believe; or whether they choose to let him in and believe. In either case, Jesus is about the final end of humans which will be done by God and is outside our control, even outside Jesus' control; that is what Christianity is about.

something being within gods control but not within Jesus is a little heretical, to my understanding of the Trinity. You might want to talk through that with your priest sometime?
