Furthermore, the exact order of the books (Matthew, Mark, Luke, and John) are specified in Zechariah, if someone cares to study Zechariah carefully. Zechariah is proof that the books of Matthew, Mark, Luke, John; are the continuation of the Old Testament, that is why I call them part of the Old Testament.
Now to you question:
Israel was elected in the Old Testament. The Church, the Body of Christ, Colossians 1:18, [not Catholic] is predestined and elected:
Ephesians 1:4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: 5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will
As believers, we preach the Grace of God to everyone who will listen, warning them of Hell and the Lake of Fire and eternal damnation. We preach because God has made us Ambassadors for Christ. Individually, we may not know who is elected; but for the love of Christ and the Father of all glory, we preach and warn and exhort all to hear the message of grace for salvation. This is not counter to Unconditional Election. I hope this helps.
Thanks for the effort but, unfortunately, it does not help me. As I see it, those that are foreordained as the elect will be saved regardless. Those that aren’t, won’t. Simple as that. Preaching is pointless.
But you have a most novel approach to the delineation of the Old and New Testaments and how that relates to election. Fascinating! I will have to think on that a while.
