The way people talk about grace, hyper-grace, if you stand in the street, get the right ideas, you are saved into eternity, no matter what you do.
Now this whole concept, no matter how much they complain is sin and relationship do not matter. So you could become a lover of satan and still be saved. But satan was condemned because of an eternal rebellion. He was given the ability else he would never have fallen. So how is it, in this world, christians who taste and walk in the kingdom of heaven cannot walk away.
So this view of grace is unversalism, but with an initial understanding or taste.
Now the counter position is we are called to walk with Jesus, and the relationship is everything. But we walk in it because it works and is real. But just like Peter, we do stumble, have issues, work through them, and keep faith.
But like couples who have an argument, it does not make them unmarried.
Now to those who say this relationship is not a marriage, why are we the bride of Christ, why do the prophets always talk about Israel being an unfaithful wife, a harlot etc. if this is not Gods language.
