Sin has it’s own issues that need to be addressed, they are lost in their current state of unbelief and evil.
That said, there’s a promise that must be fulfilled - and it will be.
He’s doing it for His Own Name - not for them.
People conveniently forget that.
1 Samuel 12:22
Deuteronomy 7:6
Deuteronomy 31:6
Romans 11:1
Agree 100%.
That said, I can't say definitively that the nation called Israel today is the nation miraculously called back from the ends of the earth in the end times.
Yet God will preserve many for that time.
