What happens the moment a person believes the Gospel?
The moment a person believes the Gospel, they become one in Christ and are in His Body. They immediately become heirs of the promises made to Abraham, not through physical descent but spiritually, as children of Abraham. Salvation is by faith plus nothing, just as Abraham believed God and it was accounted to him.
Les explains that as soon as a person becomes a believer of the Gospel, they are one in Christ and in the Body, and they then become heirs of the promises made to Abraham. He notes that Abraham's promises went far beyond the nation of Israel, and that is where believers today come in. Abraham was saved by faith plus nothing: he did not bring sacrifices for salvation, was not circumcised beforehand, and was not under the Law. He simply believed God. In the same way, those in the age of grace are saved by faith plus nothing. This ties them to Abraham, not through earthly progeny, but only spiritually as the children of Abraham.
