Source and Substance!

In Acts 20 Paul refers to his ministry as that of testifying to 'the gospel of the grace of God'. He never tired of that mission! And it is a glorious gospel full of riches beyond measure. Think of what came out of Paul's testifying: justification, sanctification, atonement, substitution, glorification, redemption, and adoption to name but a few. But Paul only testified about it(he lived it too); it was God's gospel. And God (the Father, Son and Holy Spirit) is both the source of the gospel and the substance of the gospel! The gospel has its origin in God and its composition is God!
