If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.
The gospel, resurrected Jesus is the promise God made to our forefathers.
To Abraham and his seed were the promises made. That seed is Christ.
The Lord, who created and redeemed us, summoned us by our name and made us His.
When we became believers in Christ, we were marked in Him with a seal by the promised Holy Spirit.
