What responsibility does God place on Gentiles now that the Gospel is revealed?
God lays upon Gentiles the responsibility to believe the Gospel now revealed—the message Paul calls 'My Gospel,' the Gospel of the Grace of God, and the Gospel he preaches among the Gentiles. That revealed truth is what Gentiles are to believe today.
Les explains that faith has always been responding when God speaks: Noah built the ark when God told him to, and Abraham left Ur of the Chaldees when God said to. Now, with the Gospel revealed, God lays that same responsibility upon Gentiles to believe the Gospel Paul brought out to the Gentile world. Paul calls it 'My Gospel,' 'the Gospel of the Grace of God,' and 'that Gospel which I preach amongst the Gentiles'—the revelation of the secret kept secret from ages past. So today Gentiles are to believe what God has revealed to us.
