In Romans 11:5-6, Paul makes it clear that this remnant is chosen *by grace*, just like all the rest who believe in Jesus Christ as their Savior. The remnant therefore is not saved based on their nationality or the fact that they are descendants of Israel! Of course there are descendants of Israel who have put their faith in Jesus Christ, and this is the remnant he describes. I think it’s pretty clear on this, don’t you?
Read on to Romans 11:25
What is the fullness of the Gentiles mean to you?
Yes, and beloved for the father's sake: ISRAEL: CHOSEN OR FORGOTTEN?
You make a good point. I’ll add to it with this:
Revelation 12:17And the dragon was wroth with the woman, and went to make war with the REMNANT of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
Hebrews 10:16This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;
The new covenant clearly states that God will put his laws into our hearts and minds, and we will obey Him. Those who don’t, are not His remnant, and will not be saved. They will be the ones saying “But Lord, Lord, I did this and that in your name”, etc... Those who commit lawlessness will not be in heaven. Rejecting God’s law is lawlessness. Saying it was nailed to the cross and doesn’t apply to Christians is lawlessness. Saying it only applies to the unsaved is lawlessness. Those who believe in those things have been royally hoodwinked by Satan, and they don’t even realize it.
