Galatians 3:14-16

14The purpose was that the blessing of Abraham would come to the Gentiles by Christ Jesus, so that we could receive the promised Spirit through faith.

15Brothers and sisters, I’m using a human illustration. No one sets aside or makes additions to a validated human will.

16Now the promises were spoken to Abraham and to his seed. He does not say “and to seeds,” as though referring to many, but referring to one, and to your seed, who is Christ.
