Galatians 3:6-9  :

Even as Abraham “believed God, and it was counted to him for righteousness.” Know therefore that those who are of faith, the same are children of Abraham. The Scripture, foreseeing that God would justify the Gentiles by faith, preached the Good News beforehand to Abraham, saying, “In you all the nations will be blessed.” So then, those who are of faith are blessed with the faithful Abraham.

The true children of Abraham, believe God for righteousness like Abraham did. This is the true meaning of what was written in the Old Testament when it says that Abraham “believed God, and it was counted to him for righteousness.” Another way that we can put this is that it was “credited” to Abraham with no repayment terms because he believed God.

See how important believing is to Christianity. Anyone who says otherwise is a false teacher and should be avoided. What we read here are the words of Jesus through Paul and no one can change that fact.

Isn’t it amazing that God sees Christians as children of Abraham. We were the promised children that God told Abraham he would get from all the nations. It is a very interesting thing to read the subject of Abraham and having children. It explains much of what is currently going on in the Israel today. What’s so amazing is that God sees children of Abraham that are not physically of Abraham. It’s not that He doesn’t also see the physical children (See Romans 11), but that He also includes us. It is a shame that some preachers would try to say that God has given up on the Nation of Israel. He hasn’t at all. We should not listen to those teachers either because it is very clear what Jesus thinks about Israel in both the Old and the New Testaments.

Here we also have an example of the Gospel in the Old Testament. God was planning it all along even though it was somewhat mysteriously presented in these words to Abraham. There are no accidents with God. He knows everything that is going to happen right down to you and I. Jesus says that He knows how many hairs we have on our heads and when every sparrow dies. Not only does He know everything, He has planned everything and it is revealed in the Bible even if people don’t see it at first.
