All Nations Will be Blessed
The original, and ancient gospel is stated in Galatians as what was told to Abraham, two thousand years before Jesus was born. It is namely, (as stated in Genesis 12) The LORD said unto Abram... I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing: And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed." God explains a little later that this also means all nations "Seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him?" (Gen 18:18) In the ancient book of Malachi, it also says "All nations shall call you blessed, for ye shall be a delightsome land, says the LORD of hosts". (Mal 3:12). Blessing to all nations is what is the true and ancient gospel that was preached by Christ, and preached to Abraham. The apostle Paul also explained this in Galatians 3, when he said "And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed." (Gal 3:8). God's promises involve a government, a Kingdom that will be established on earth and will bring blessing to all the nations in the world when Jesus is King of Israel in Jerusalem.
In Ezekiel 30, God says that nations are as trees. The Assyrian was a large cedar in Lebanon, which beautiful branches. It was a tall tree with strong and long branches, many birds came and lived in the branches of this great tree. The roots of this tree extended far, out into the great waters. Other trees, cedards, chestnuts and fir trees were nothing in comparison to this great tree. God compares the nations around that world, to trees in His garden of Eden. But that tree lifted itself up in pride and had to be brought down low. The giant trees get felled by God. Cut down. They fall, and go into the ground. Nations are compared to trees. That was the ancient way, and the way God established by starting the world with a garden.
