The Book of Galatians reminds the Church to embrace and follow the gospel message of the crucified Messiah. The requirement for non-Jewish Christians to become Torah observers and be circumcised or eat kosher misses the point. Jesus alone fulfills the laws of Torah and justifies believers.
When people trust in Jesus as Messiah and put their faith in Him, His life, death, and resurrection become theirs. They are new creations, free from the requirement to follow the laws of Torah.
They now join a new multi-ethnic covenant family of Jesus, thus fulfilling God's promise to Abraham. Because of Jesus and the Spirit, believers learn to love God and others.
