Simply say this one thing: you must make an active attempt reject sinfulness to receive full grace in Judgement.
For some reason there will almost always be a few pop up to rebuke you. They'll incorrectly quote scripture, call you names, invoke the thief on the cross and generally act like their so, SOOOOO holy. Under all of their rhetoric this is what they are saying..
You can do whatever you want and still go the Heaven. Are you a drunkard? Saved. Gambler? Saved. Womanizer? Saved. Are you a pervert? Saved. Commit child sacrifice? Saved. I mean after all, these same people tell us all sin is the same and one sin is as great as all sin, right? So why would a gambler go to Heaven but not one who commits child sacrifice? This is incorrect teaching btw.
This is the truth. These people are either jews or coping. Either they want to lead others into sin or they are already in sin. In the latter case, they see themselves named in Romans 1 and are heavily distressed.
These people are little more than a stumbling block. Reject them as being un-Christian and degenerate.
The implication that I have received endlessly debating against this philosophy is that if you are "saved" then you can do no wrong. That's it, you're saved. "Do nothing, Heaven Guaranteed." No more work, no more charity, no more virtue, no more resisting temptation. You're saved. This is the lazy theology spewing from these supposed churches.
Salvation can absolutely be revoked if you fall back into temptation. It is not a one way ticket to feel good land, the Kingdom of Heaven is a constant struggle against devils and carnal lusts. A Christian must strive to become the greatest man that he can be in the eyes of God. Of course he will fall short. I fall so short, brother, so very short. There is certainly forgiveness (Grace) where humility and self-punishment is found (hence ashes and sack cloth in the OT), but to fall back into what you understand and know to be sin is an atrocity against both self and Creator. Only in death will we be truly freed from the woes of this world.
God will provide strength to overcome these things if you ask.
I think we agree though that grace isn’t just a safety net like a lot of people seem to treat it.
This starts working into predestination territory. Why would one who genuinely calls on Jesus be saved but another not? I unfortunately have to ward off sin every day of my life. For a moment, I fell back into a sin that I previously conquered. Through prayer and promise to the Lord I have managed to keep away from it, though the temptation never subsides. God forbid that I die in that sin.
Faith must be maintained and tempered. We see the theme used in the story of Abraham, who proved righteous, Job, who proved faithful, and in Exodus. In the latter case it was intercession which saved the Israelites.
