Your position seems to be that if someone does not get baptized, s/he will not be saved. That means that if for some reason a believer on Jesus Christ never arises from a baptism, s/he will not be pardoned for sins committed and faces condemnation.
First, John 3:16-8 spoken by Jesus Christ regarding Himself
“For God so loved the world, that he gave his only begotten Son, that whosoever believeth on him should not perish, but have eternal life. For God sent not the Son into the world to |condemn| the world; but that the world should be saved through him. |Whoever| believeth on him is not |condemned|: he that believeth not hath been |condemned| already, because he hath not believed on the name of the only begotten Son of God”
My beliefs are not contrary to this scripture at all. My views are simply that belief in Jesus alone does not save us, which does to you sound contrary to what Jesus is saying. But if what I just said is contrary then what James 2 says is contrary (James 2:20 But wilt thou know, O vain man, that faith without works is dead?). I don't believe these to be contrary to John 3:16, neither do I believe any of the scriptures are contrary to one another, but rather that they are all credible. One scripture may describe one thing without mentioning the other and that other thing may get mentioned later on in another scripture, but they all work together. Like it says in
Isaiah 28:13 But the word of the LORD was unto them precept upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little; that they might go, and fall backward, and be broken, and snared, and taken.
So putting John 3:16 and James 2:20 together into one concept along with everything else I said concerning all the scriptures being coherent, I've come to the conclusion that just because you believe, doesn't mean you are guaranteed salvation. You must believe in Jesus the Christ, repent from your previous works and get baptized in the name of Jesus. All these things working together not wavering.
Oh keep in mind that the devils did also believe... was Jesus saying that they are also not condemned?
Acts 10:43, spoken by Peter,
"To him bear all the prophets witness, that through his name every one that believeth on him shall receive remission of sins" (ASV).
The passages state explicitly that belief on Jesus Christ assures no condemntation and guarantees remission of sins. Your position, contrary to these passages, seems to be `If a believer on the Lord Jesus Christ never gets baptized, s/he will not be saved, will not get remission of sins, and is condemned.'
I think all that I said above applies here also. I just want to add that for a person to believe in Jesus he must accept and do all that he says and all that his apostles say to do because he sent them. Belief doesn't just stop at saying "I believe in Jesus and accept him in my life", it constitutes an action. So if I believe in Jesus I will repent, and be baptized for the remission of my sins. That is how by belief you are guaranteed remission of sins, because your confidence in Jesus will allow you to humble yourself to his commandments (and the apostles). And as I stated before , "who are we to say who will be saved and who won't" because the scripture says
Romans 9:15
For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion.
