In this we see that the Gospel reveals an inheritance; in fact, the mystery of the Gospel is really the possession of the inheritance, because in Him we have obtained an inheritance. Now let us see how the matter is stated in the eight of Romans. We shall not quote the scripture entire, but simply summarize it. EVCO 29.9
Those who have the Holy Spirit of promise are sons of God; “for as many as are led by the Spirit of God, they are the sons of God.” But if we are children we are necessarily heirs; heirs of God because sons of God. And if heirs of God, we are joint heirs with Jesus Christ. The one thing above all others that Christ is desirous that we should know is that the Father has loved us even as He loved Him. EVCO 29.10
