I believe Jesus Christ is God (Ho Theos), but believing this is not a salvation issue. One can believe in the Trinity but not know God or Christ. It's perhaps what they were taught but there is no relationship involved. It's not believing Jesus is God that saves; it's treating Jesus like God that saves; honoring Him as we do the Father, calling on Him for salvation, sharing with Him our cares, receiving Him, whose name alone under heaven can save.
Jesus invites us into personal relationship with Himself. "Come unto Me and I will give you rest"...salvation, forgiveness, righteousness, holiness and life eternal.
