From La Palma, California.
The gospel is plainly presented. If Christ is not risen, then our proclamation of the cross of Christ is empty, and our faith is empty. But Christ is risen! He is the firstfruits of all those who have died. Believers will be resurrected and changed; in a moment, in the twinkling of an eye. All because of Christ.
As Paul concludes his letter he is excited about an effective door of the preaching of gospel being opened to him. Yet he warns there are many adversaries.
