Thinking it all happened in AD 70 does not preclude a literal return of Christ at the end of the present Gospel age of grace. .
The final coming, the return of Christ will be at the end of the present Gospel age of grace. All will know it, the living, the saved dead, & the unsaved dead. All will rise at his coming in the sequence indicated in 1 Cor. 15.
The AD 70s coming is taught by the Lord Jesus in his Olivet prophecy which would take place in the lifetime of the generation that rejected him. Those "days of vengeance" brought to absolute end of the corrupt nation of Israel.
However, the Covenant "holy nation" of Israel was restored when at Pentecost when thousands of Jews & other dispersed Israelites from all round the empire responded to the NC Gospel message. thousands more were added, continually, including priests & Pharisees.
Exo. 19:5 Now if you obey me fully and keep my covenant, then out of all nations you will be my treasured possession. Although the whole earth is mine, 6 you will be for me a kingdom of priests and a holy nation.” These are the words you are to speak to the Israelites.’
1 Peter 2:9 But you are a chosen people, a royal priesthood, a holy nation, God’s special possession, that you may declare the praises of him who called you out of darkness into his wonderful light. 10 Once you were not a people, but now you are the people of God; once you had not received mercy, but now you have received mercy.
Y1, you do specialise in writing absolute rubbish.
Saved Jews & Gentiles become together the believing seed of Abraham by faith, the Israel of God, not by circumcision nor ethnicity but by faith in Christ.
Try reading the whole of Romans, not just a few verses in Rom. 11. If you include Rom. 15 in your reading, you will see these verses -
7 Accept one another, then, just as Christ accepted you, in order to bring praise to God. 8 For I tell you that Christ has become a servant of the Jews on behalf of God’s truth, so that the promises made to the patriarchs might be confirmed 9 and, moreover, that the Gentiles might glorify God for his mercy. As it is written:
‘Therefore I will praise you among the Gentiles;
I will sing the praises of your name.’
10 Again, it says,
‘Rejoice, you Gentiles, with his people.’
11 And again,
‘Praise the Lord, all you Gentiles;
let all the peoples extol him.’
12 And again, Isaiah says,
‘The Root of Jesse will spring up,
one who will arise to rule over the nations;
in him the Gentiles will hope.’
13 May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit.
Looking for an earthly future for carnal Israel amounts to a rejection of the fulfilment of God's Covenant promises in the Lord Jesus Christ through the Gospel.
