If you knew about it you could post a scripture that says experience trumps obedience or that one feels saved before he obeys. John wrote that it is knowledge that trumps emotions and feelings as did every other New Testament author. I can only imagine what Peter's sermon on the day of Pentecost would be like if this unfounded assertion of yours were even remotely true.
"Men, bretheren, what shall we do?"
"Then Peter said to them, when you get the feeling that you are saved, just go on about your lives however you are led by your feelings. If you don't feel some type of way, then you're not predestined to be saved. You're going to hell. You weren't one of the elect. Those of you who feel like you've been saved will probably believe me and go to heaven. But even then, it's not such a plain thing. If you find yourself committing a sin, then you obviously are not saved and are going to hell. Sorry but that's just the way God works. If it seems unfair, just remember that God's ways are sovereign. If he made you to be a sinner and to go to hell, then at least be the best sinner you can be."
If one's personal feelings was the proof of salvation and we are saved against our will, as Calvin professed, then the words of the New Testament are superfluous. We don't need them at all. Certainly you don't seem to need them. You just make unsupported assertions as if they are true.
