Church teaching is that we are now in the New Covenant.
This belief mainly comes from Luke 22:20 In the same way, He took the cup and said: This cup, poured out for you, is the new Covenant, sealed by My Blood.
But Luke 22:20 is a later addition to scripture and is not found in the early manuscripts. It is deleted by the Revised English Bible and others.
Can we Christians today really say we experience all the results of the New Covenant, as listed in Hebrews 8:10-12?
1/ I shall set My Laws in their hearts.
2/ I shall be their God and they will be My people.
3/ They will not teach each other, for all will know the Lord.
4/ I shall pardon their sins and remember their wickedness no more.
Not one of these things are fully in effect now, or have been since Jesus was on earth. They are all yet to happen in the future.
The Old Covenant was made between the Lord and the Israelite peoples:
Exodus 24:3-8, where all the Israelites heard the Laws in the Book of the Covenant and promised to obey them. It will be the same again, in the end times, when all of the Lord’s faithful people will be living in the holy Land.
Proved by how it is only then that the sins of the people will be forgiven. Isaiah 33:24
The big sticking point with this scenario for most is all the Christians going to live in the holy Land. They have been taught that the Jews remain there while they avoid the Lord’s wrath by being raptured to heaven, plus the idea of migrating to the Middle East is totally unheard of and isn’t at all desirable as it is now.
Many prophesies say how the Lord will regenerate the Land and it will become like the garden of Eden. Ezekiel 36:8, Isaiah 35:1-10, Jeremiah 33:12-13
We Christians are the Lord’s witnesses, Isaiah 43:10, John 15:27 and His Light to the nations. Isaiah 49:3-8, Matthew 5:14-16 We have His Commission to proclaim the Gospel until Jesus comes again. Matthew 28:19-20
Many prophesies tell us that the current Jewish State of Israel will be gone after the Lord’s Day of fiery wrath. Jeremiah 12:14, Zephaniah 1:1-18, and only a remnant will remain. Isaiah 29:1-4, Romans 9:27
They will be joined by their Christian brethren, Jeremiah 50:4-6: His lost sheep, Ezekiel 34:11-16, all the vast multitude in Jerusalem seen by John. Revelation 7:9
There: Jesus will make the New Covenant with us, for our peace and prosperity. He will demonstrate His power to protect us: by the destruction of the Gog/Magog army.
That the Lord’s holy people are present in the holy Land before Jesus Returns, is proved by Daniel 7:25 and Revelation 13:7, when the ‘beast’ conquers them. Zechariah 14:1-2 However, some of the Christians will violate the New Covenant and agree to a peace treaty with the leader of the World Govt, Isaiah 28:11-12, as described in Daniel 11:32, which will commence the Great Tribulation for the final 3½ years before Jesus Returns.
