Actually some things are perfectly true, but other things in your list are false.
However since this thread is about the Old and New Covenant, you claim that "
The New Covenant is [NOT] in effect for the Church today" is false. We could go into a lot of detail as to why your assertion is false, but the recorded words of Christ from Matthew 26 are sufficient:
27 And he took the cup, and gave thanks, and gave it to them, saying,Drink ye all of it;
28 For this is my blood of the new testament [covenant], which is shed for many for the remission of sins.
29 But I say unto you, I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in my Father's kingdom.
So did the shed blood of Christ ratify the New Covenant and did His death usher in the New Covenant? Absolutely.
You can try and contradict what was said above but it will hold no credibility.
I agree with much of that..
But consider this - in the NEW Covenant we have this (as we see in Hebrews 8)
“Behold, days are coming, says the Lord,
When I will effect
a new covenant
With the house of Israel and with the house of Judah;
9 Not like the covenant which I made with their fathers
On the day when I took them by the hand
To lead them out of the land of Egypt;
For they did not continue in My covenant,
And I did not care for them, says the Lord.
10 “For
this is the covenant that I will make with the house of Israel
After those days, says the Lord:
I will put My laws into their minds,
And I will write them on their hearts.
(So that is the New Birth, New Creation, New Heart, old things passed away all things become new)
And I will be their God,
And they shall be My people.
(So that is adoption - "
to as many as received Him to them He gave the right to be called the children of God" - John 1:12)
11 “And they shall not teach everyone his fellow citizen,
And everyone his brother, saying, ‘Know the Lord,’
For all will know Me,
From the least to the greatest of them.
(Spirit of Truth as the teacher - "
leading in to all truth" John 16)
12 “For I will be merciful to their iniquities,
And I will remember their sins no more.”
(Forgiveness of sin - 1 John 1:9 )
Which is the "ONE Gospel" of Gal 1:6-9
Which is the "Gospel preached to Abraham" Gal 3:8
And as Paul said in Hebrews 4 "
The Gospel has been preached to us just as it was to them also"
In Matthew 17 - Moses AND Elijah stand with Christ "in glory" before the cross -- on the mount of transfiguration --- fully forgiven even before the cross, saved under the one-and--only Gospel preached in OT and NT.
