Now the promises were made to Abraham and to his offspring. It does not say, “And to offsprings,” referring to many, but referring to one, “And to your offspring,” who is Christ. Gal 3:16

The LORD appeared to Abram and said, "To your offspring I will give this land." So he built an altar there to the LORD, who had appeared to him. Gen 12:7

For as in Adam all die, so in Christ all will be made alive.
1 Cor 15:22

Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers; But with the precious blood of Christ, as of a lamb without blemish and without spot: The precious blood of Christ was not corrupted.   1 Peter 1:18-19
