I wrote my answer down. And then I asked hubby, (who does get Reformed Theology better than I do), and something happened after that, so I got delayed in finishing this.
I'm going to give all three things as an answer:
1. My answer: Well, not really. Trump was elected. Think he stopped sinning? lol
Same thing with us. We're elected/chosen. We are the children of God. Adopted by the King of Kings. Don't we still act like little brats at times anyway? We still sin. We're just over the sin-nature, so we know we're sinning. It's no longer blindly sinning by nature.
Once elected though, God doesn't change his mind. Remember Jonah was elected. If we don't behave like we're supposed, God gets us there anyway.
I do believe OSAS, but I don't know if that's Reformed, or not. The big question after that needs to be asked though -- Are you really saved? King Saul seemed saved for a while. So did Judas. They seemed saved. Now it seems like they never were saved.
2. Hubby's answer: OSAS is a cheapened response for "Perseverance of the Saints." It's the Armenian's answer to what we're saying. We are saved, if we persevere. If we don't persevere, we weren't saved. Then he gave an example of someone in our family's belief. She said her grandmother was saved because she made the alter call at a Billy Graham Crusade. That's what saved her. Walking down to the front to be prayed over. But nothing changed for the rest of her life, so she wasn't saved.
He used something David said, (but it's a couple hours later, so can't remember it enough to quote him exactly.) David asked God where he could go to leave God, since even in the depths of Hades, God is. David couldn't escape God, so he persevered.
God changes us so much so that he has us persevere. If we don't, then God didn't change us.
3. The thing that interrupted this:
Not related to this at all, except PennEd (a fellow CCer) stopped by with his friend Rich. They're going to help us work on our house. The Lord called him to help us in this way, and wow! I really had some ideas on how they could help, but they have even more ideas.
He asked me in what way they could help, and I immediately thought about our front window. It's huge and falling apart. It's so bad, I think the only reason it's staying in is because of God's providence. But I didn't ask that one, because we have some idea how much it would cost to replace it, and way too much to ask. I really thought the only choice was replace it, but Rich (Ed's friend) thinks it can be fixed and repainted. I was just thinking of having them take old stuff out we can't lift. So, kind of like thinking someone was going to give us a used car that works, but being offered a new car. Much much bigger than I thought, and I was very excited over my thought.
Trying hard not to cry over this, (hubby is too), but what a wonderful God we serve!
