Galatians teaches that believers are justified by Jesus alone. They are a part of a diverse family and equipped by the Spirit to love God and others.
In the book of Galatians, believers learn that they are justified by the Gospel of Jesus, not the laws of Torah. They are a part of a multi-ethnic family and equipped by the Spirit to love God and others.
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, fulfilling God's promise to Abraham.
