Acts 15:10-11: “So then, why do you now want to put God to the test by laying a load on the backs of the believers which neither our ancestors nor we ourselves were able to carry? No! We believe and are saved by the grace of the Lord Jesus, just as they are.”
Peter says this to the Jewish believers who were Pharisees when they got saved. (Remember, there were lots of different sects in Judaism at the time. The Pharisees are the ones who preached about obeying the Torah–the Law of Moses).
These Pharisees wanted the Gentiles to be circumcised and follow the Law of Moses. The problem with that, Peter noted, is that we “are saved by the grace of the Lord Jesus,” not by our works, or what we do.
I see a theme of inclusion in the Book of Acts. The Holy Spirit levels the field between Jews and Gentiles, so that all are equal before God. Not only that, but it shows that we had nothing to do with this to begin with, so why would we have to do something in order to keep it, or to belong?
God is pleased simply by our faith. On the most basic level, faith is all God requires of us. And I believe that it is our faith in God’s story, the Gospel, that will make everything follow–the hope, the love, the obedience, etc.
