As Pastor Johnny continues his teaching through 2 Thessalonians, he'll be reminding you that simply believing in a doctrine isn't the same as having saving faith in Jesus for your salvation. Even the demons believe there's a God and they are destined for Hell. It's more than having an intellectual understanding of the doctrine of salvation and of who Jesus is. You need to have a saving faith in Jesus which leads to obedience to Him. The only proof of salvation is having a transformed life.
