Again, you're completely missing the point...
The point is that God kept believers for Himself. It isn't that there were 7,000 who hadn't worshiped Baal. It was (and is) that God kept this remnant for Himself.
The reason they hadn't worshiped Baal is because of God's intervention, not their own free will.
The Archangel
Must you read election and predestination into every passage?
Did God take blind-folds and blind these men that they could not see any altars of Baal?
Did he tie their feet that they could not go to any of their altars?
Did he take away their comprehension that they could not think of these false gods?
Or perhaps, just perhaps, it is of their own free will that they chose not to serve Baal, and chose to serve Jehovah instead--as did Elijah. No one compelled or forced them.
Consider once again the historical setting.
Elijah had won a stunning victory in defeating 450 prophets of Baal and convincing Israel who is the real God:
1 Kings 18:39 And when all the people saw it, they fell on their faces: and they said, The LORD, he is the God; the LORD, he is the God.
But when Jezebel heard of it, she threatened Elijah's life and Elijah ran in fear and became discouraged. God comforted him, speaking to him:
1 Kings 19:12 And after the earthquake a fire; but the LORD was not in the fire: and after the fire a still small voice.
1 Kings 19:16 And Jehu the son of Nimshi shalt thou anoint to be king over Israel: and Elisha the son of Shaphat of Abelmeholah shalt thou anoint to be prophet in thy room.
1 Kings 19:18 Yet I have left me seven thousand in Israel, all the knees which have not bowed unto Baal, and every mouth which hath not kissed him.
In the above verse--the KJV--the word "me" is not in the Greek.
Look at a couple of other translations:
(MKJV) Yet I have left seven thousand in Israel, all the knees which have not bowed to Baal, and every mouth which has not kissed him.
(YLT) and I have left in Israel seven thousand, all the knees that have not bowed to Baal, and every mouth that hath not kissed him.'
He is simply saying: "I have left 7,000 in Israel..." They were men, who of their own free will, did not bow their knee to Baal. God is reassuring Elijah that he is not the only one standing there and serving God. There are others doing the same work.
There also will be Jehu and Elisha to add to the leadership.
Now look at some biblical principles:
1 Corinthians 10:6 Now
these things were our examples,...
1 Corinthians 10:11 Now all
these things happened unto them for ensamples: and they are written
for our admonition, upon whom the ends of the world are come.
--Paul uses a number of OT historical examples as illustration to teach NT truth.
He does the same thing in Romans chapter 11.
Romans 11:1 I say then, Hath God cast away his people? God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin.
2 God hath not cast away his people which he foreknew. Wot ye not what the scripture saith of Elias? how he maketh intercession to God against Israel, saying,
--Paul first identifies with the nation of Israel himself.
Has God cast them away, replaced them, or do they still exist?
In no uncertain words Paul, identifying with Elijah, and says that Israel still exists. He identifies them as "his kinsmen" in Romans 9:1-4 and 10:1-4.
If anything this passage strongly refutes those who believe in replacement theology or any similar doctrine. Israel still exists. Paul was acknowledging its existence then, and a remnant would continue to exist in the future. The would always exist. God would make sure of that.
Paul was an Israelite, and he would not be the only one.
Romans 11:3 Lord, they have killed thy prophets, and digged down thine altars; and I am left alone, and they seek my life.
4 But what saith the answer of God unto him? I have reserved to myself seven thousand men, who have not bowed the knee to the image of Baal.
--He refers back to the story of Elijah.
Romans 11:5 Even so then at this present time also there is a remnant according to the election of grace.
6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work.
--Even now, now during the time of Paul does Israel exist. Israel has not been replaced by the church or by Christianity. Christianity or "the Church" is not a continuation of Israel. Israel as an entity in and of itself still exists. Again, it is a blow to the "Replacement Theology" idealists. There is a remnant now, and there will be a remnant in the future whether or not they have now received the Messiah is not relevant at this present time.
But in the future they will receive the Messiah (verse 26).
--Elijah should not have been discouraged; neither should we. Israel still exists and she still will be here when Christ comes again. This is all of God's grace, not of any work on Israel's part as is so emphasized in verse 6.
