The promise to Abraham and his descendants as the inheritor of the earth came through

The promise to Abraham and his descendants as the inheritor of the earth came through the righteousness of faith. This means that God promised Abraham and his descendants that they would inherit the earth not because of their works, but because of their faith in God. In other words, their trust and belief in God's promises made them righteous in His eyes, and it was through this righteousness that they would receive the promised inheritance. This concept of righteousness through faith is a central theme in the Bible, and is particularly emphasized in the New Testament.
