The elect are children of the kingdom. Those thrown out are children of the kingdom.
Matthew 8:12 But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth. |
Those cut off are original branches, hence, elect. Those grafted in will also be cut off if they don't continue in His goodness:
NIV Romans 11:19-22
19 You will say then, "Branches were broken off so that I could be grafted in."
20 Granted. But they were broken off because of unbelief, and you stand by faith. Do not be arrogant, but be afraid.
21 For if God did not spare the natural branches, he will not spare you either.
22 Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise, you also will be cut off. |
Scriptures are clear. Among the elect, there are those who will be cut off and thrown out. But only God knows who.
