I certainly don't agree with universalism. But wasn't Israel chosen to be a nation of evangelists for the masses? Of course they failed, but through their many dispersions, I believe the faithful did evangelize. Jonah is one example. Though he wasn't part of any dispersion.
Of course they evangelize ... but what exactly DID they evangelize?
Grace and faith are the backbone, but what did they teach exactly?
Here is the way I understand their teaching ... step-by-step throughout the OT.
1. There is One God, the Almighty.
2. Unlike the demons and other gods (same thing), God is good.
3. We are sinners.
4. We want Heaven yet cannot reach it on our own.
5. Our situation is hopeless. Sheol awaits us and the best corner of Sheol is the environment of sadness.
6. YET, because God is NOT like demons, and because God is GOOD and God is LOVE, He HIMSELF will save us ...
That is the Gospel preached to nations, the way I understand the OT.
I don't see any appreciable difference between grace and faith at any time.
Same formula different application.
Yes, these clearly are different. For example, the indelling of the Holy Spirit wasn't for all believers in the OT. Very few were indwelt. David prayed that God would not take the Spirit from him. But Jesus promised that the Holy Spirit would be given to all believers permanently.
Of course.
Just one of the examples.
Yes. But remember, heaven is temporary. Rev 21 speaks of this present heaven and earth passing away and God creating a new heaven and earth post-Millennium, and heaven will come down to earth.
True.
But there is also Heaven where God dwells.
A place WITH God.
And Christ promised us "rooms" (actually rather large rooms
) where we will be WITH Christ.
Christ is in Heaven and we will be with Him.
And new Heavens.
Sure, but we would then live in the New Jerusalem during this major construction and renovation.
Some say New Jerusalem is a cube, but it is not a cube.
It is of the shape of pyramid.
The only shape of New Jerusalem as described in the Bible could be either a cube or a pyramid.
Since Christ is the Cornerstone and Capstone - pyramid.
Of course, Satan is trying to use his own pyramids, Egypt and all, but that's another topic.
Fascinating topic, however.
