Greetings.
We will continue our examination of Galatians 3 today. In verses 6-7 we looked at how Abraham beleived in God's promises and it was credited to him as righteousness. Paul continues using Abraham to make his arguments in verses 8-9. Here is my translation:
8 The Scriptures foretold this, seeing beforehand that God would justify the Gentiles, by faith. He preached this gospel ahead of time to Abraham, “Through you all nations will be blessed.” 9 So then, those who have faith are blessed right alongside Abraham, the faithful one.
God had, indeed, chosen the Israelites to be his people. However, within their role as His chosen people, they were to be a light to the Gentile nations. (See Isa. 42:6, 49:6) They were supposed to show the rest of the world the way to God, but this was a role that they never really seemed to understand. Anyway, Paul says in verse 8 that in the Scriptures, going all the way back to Abraham, this development had all been foretold.
According to Paul. when God promised Abraham that through him all nations would be blessed, back in Genesis 12:3, God was foretelling that the time would come when God justified, even Gentiles, through their faith. The promise was not that just Abraham’s descendants (the Jews) would be blessed, but all nations would be. Paul is saying that from the beginning it had been God’s intention to bless and include the Gentiles into His kingdom. So, those who have faith, regardless of ethnicity, are children of Abraham, and are blessed right alongside him (verse 9).
Paul’s discussion of Abraham certainly provides us with a scriptural basis for the inclusion of Gentiles into God’s kingdom, but more importantly he is using Abraham to show that the blessings of God, for Jew and Gentile alike, are accessed through our faith rather than through obedience to the Law. (Moo, 200.) John Stott further points out that we are doubly blessed, we receive justification (verse 8), but we also have the gift of the indwelling of the Holy Spirit. (verses 2-5). These two gifts come to us together. (Stott, 74.)
In his commentary on Galatians, Thomas Schreiner makes a valid point. When Paul talks about Abraham’s faith, he is not talking about “an abstract belief in God, but belief in God’s promises.” (Schreiner, 194.) It is the same for us. Our faith must be more than belief in God’s existence, but a genuine belief that His promises are good and they will be kept. This is place where you have to ask yourself, "Am I really trusting in God's promises?" Of course, this is where it gets difficult. Those who believe God’s promises will act on that belief, but it is not the doing that God recognizes, it is the believing.
Schreiner further points out that verse 7 and verse 9 may seem repetitive, but the message is slightly different, telling us first that faith makes us children of Abraham (v. 7), and secondly, that faith allows us to share in Abraham’s blessing (v. 9). (Schreiner, 195.) So, in this short section going from verses 6 to 9, we can see two very important, and very cool things that come from our faith. 1) We become children of Abraham and 2) we share in his blessing.
