So are you saying that if no fruit comes from a believer then he will no longer be saved?
No, rather I'm talking about nature. Whether a believer produces fruit doesn't change the tree. For me: the parable of the unfruitful tree
Luke 13:6-9;
23:39-43 and coupled with it, ideas like Ephesians 2:10 Hebrews 12:5-14 1 John 3:3, there is just no way that isn't eventually going to happen. It isn't that you or I couldn't fail. It is rather the Lord Jesus Christ cannot.
And you said nothing about what I said previously:
Since the LORD knows the heart of men (1 Ki.8:39) He knows who has true faith and those who don't. To those with true faith He gives eternal life (Jn.5:24). And the Lord Jesus says that those to whom He gives eternal life shall never perish (Jn.10:28).
Therefore, from the moment when a person believes the gospel he is eternally secure.
Well, before this additional comment, I agreed with everything. On this, I'd rephrase if you'd allow: "The moment the Lord Jesus Christ saves a person" rather than a person's belief. It may seem a bit nitpicky, in my thinking, the gospel is about the Lord Jesus Christ having a hold of me, rather than so much me having a hold of Him. 1 John 5:12 has it as we have a hold of Him, but only in Christ are we new creations.
I know a couple of guys who have told me they are into 'fire-insurance' and have no intention of following the Lord Jesus Christ, by their own words. They rather prayed the prayer. I have no idea how to respond to that guy and the others like him. Luther said to 'sin boldly' but was he talking about something like this as well? For me, a great comfort is not so much that I called upon Him, but that He prepared and responded: He has a hold of me.
By another example, I have a couple of friends on TOL that others would think: "What????" Others don't see their fruit. I see it. One of them taught me grace undeserved is grace indeed. Another, that I should love the Lord God my Savior, Jesus Christ and give Him praise and honor only worthy of His Holy Name. I tend to see fruit where another may not. Maybe they don't even see it in themselves. The parable of the sheep and goats has many questioning "when Lord? Where did I do this Lord?"
It may be that one could desire the gift, rather than the Giver. Perhaps that one is saved as though escaping through flames, but isn't he/she the sad one? I'm not talking about trying to do for God, like Martha, but rather talking about being with Him, like Mary.
