What exactly is the Blessings of Abraham that the Father promised us through him?

Reading in Gen.12: 2 we are told “And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:
3 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”.

The Blessing is for the whole families of the Earth, Jews and Gentiles. Mongolians, Indians, Japanese, Eskimos alike, none excluded. But what exactly is this blessing. Can we say all have received and are receiving this blessing now? If not why? .Could this be just material blessings alone? If so then, the western world, and Asia Nations are more of the seed and inheritors of the Abramic Blessing as compared to most Africa Nations.

Again, in Gal.3: 7 we read “Know ye therefore that they which are of faith, the same are the children of Abraham.
8 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….
29 And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise.”

Here Paul explains that, the Children of Abraham to whom the Blessings are geared towards are those who are of faith in Christ.

Now, most of those wealthy Nations on Earth today are not of the faith in Christ. So how are they blessed and what blessings therefore do they have. How do they come into all these Blessings materially and yet most who claimed to be of the Christ faith are not, if this is the Abraham’s blessings.

I think the answer is in the Book of Acts as declared by Apostle Peter. Here it is

Acts 3:24 “Indeed, all the prophets from Samuel and those who came afterwards, as many as have spoken, also promised and foretold and proclaimed these days. 
25 You are the descendants (sons) of the prophets and the heirs of the covenant which God made and gave to your forefathers, saying to Abraham, And in your Seed (Heir) shall all the families of the earth be blessed and benefited.
26 It was to you first that God sent His Servant and Son Jesus, when He raised Him up [provided and gave Him for us], to bless you in turning every one of you from your wickedness and evil ways.” Ampl.

So then, the Abraham’s Blessings primarily was and is the forgiveness of our sins through Christ. This is what the Jews got first when Christ was raised from the grave and poured out the Holy Spirit.

Therefore if you have received Christ, then your sins and iniquities in Adam even those of your great grandfather are forgiven you and forgotten by God. You are a blessed seed of the Father; haven received you back to himself as a son through Christ. Now you are an heir of God and joint heir with Christ.

So, how is it that, the other nations without Christ are so prosperous?

The answer to that again lies in the fact that there is a common grace of God, which says the rain falls on the just and the unjust. Just as the sun rises upon everyone irrespective of their belief.

But above all, they are active and creative in their minds, for when Adam (mankind) fell, the creative power of the mind was not taken away from man. We are only asked to renew the mind (Rom 1:1-2) God himself testified to the power of a creative mind when men was to build a tower of Babel up to Heaven in Gen 11

.vesre 6 says;
“6 And the LORD said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do.”

The word “imagined” tells us of the creative power of the mind which is found in the soul of a man. 
This I believe is what most Christians have missed out of. While God is committed to answering your prayers, he is obligated to bless the WORKS of your hands.

Meaning if you have nothing doing, he will have nothing to bless even though you have been blessed in Christ with your sins forgiven, poverty will be staring you at the face.

And to overcome this, you must as a believer operate kingdom principles.

Math.6:33 “But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you”

You can’t be in the kingdom and do Business like those outside of the kingdom. No!
I called you blessed of the lord.
Just a thought!
