A good article HERE from Steve Fuller on how we are to understand the "warning passages" of the New Testament. A snippet:
Picture the road to heaven as a steep mountain road, with treacherous turns of sexual temptation — turns with such steep drop-offs that — if we fall — would mean eternal destruction.
When God saves you, and places you on this road to heaven, He promises to keep you on this road — which means nothing can pluck you off this road — nothing can cause you to fall from this road.
But if this road has treacherous turns of sexual temptation — how can He promise to keep you on the road?
Two reasons –
One is because at every treacherous turn He’s posted a warning — “If you come near — you could fall to eternal destruction.”
The other is because He’s changed your heart so you pay heed to His warnings.
By God’s grace — every saved person will respond to God’s warnings and turn back before going over the edge to destruction.Read the rest HERE.
