So a Biblical understanding shows salvation by faith instituted (based on faith in the gospel of Jesus Christ), and Abraham made righteous by his faith in Christ prior to there being any law in existence, and even prior to being circumcised (Rom 4:10), so it clear that salvation by grace through faith is apart from the law. The law was put in place to point us back to faith.
The promise in Galatians 3 and 4 is of Christ and the covenant of faith. In Galatians 3-4 Paul says there were two covenants; 1)The Works of the Law and 2)Faith. In Galatians 4 he demonstrates that even The Law says to cast out the Law because those who inherit based on The Law would not be heirs with those who were saved by faith.
The Law is how Jesus qualified as righteous, having inherited death because of the curse (Romans 5:12). He was the only one who never sinned.
So there was only ever 1 Gospel.... the gospel of Jesus Christ
