The devils do not believe the Gospel. They believe that there is ONE GOD. This is Monotheism. This is what James is speaking about. James is not speaking about believing the Gospel, but rather about believing there is One God and believing that there is a Judgment coming. That is what the context of James 2 is showing.
All a person has to do to be saved is BELIEVE THE GOSPEL. Once a sinner is under conviction, all they need to do is believe on Jesus Christ, trusting alone in His finished work which He did for them at Calvary. And that's all. Once a person has believed the truth of the Gospel, that person is instantly saved and born again.
And yes, God does only save sinners. And the reason that a person must come under conviction, is because Conviction is where the person sees himself as he what he really is, which is a lost sinner before a holy God. Once that sinner is convicted, now all he needs to do is repent of his unbelief and believe the Gospel, and he will be saved.
Also the tests in 1 John are not tests to see who is saved and who is lost. But rather, the tests given in 1 John are to determine which born again Christians are walking in the Spirit (Light) and which born again Christians are walking in the flesh (Darkness).

John 1:12 says that it is necessary to receive Christ in order to be born again. Now no one is going to receive if they do not believe. However, I know a few people who agree with the facts of the gospel but who have yet to receive Christ. My own daughter is one. I wish it were different, obviously. Ask her and yes, she believes. But there is no reality of salvation. She has yet to receive.
