God said that He Himself was Abraham’s reward. If we are Christ’s, then we are Abraham’s seed, and heirs according to the promise. Heirs of what?—“Heirs of God, and joint-heirs with Christ.” 1Romans 8:17. EVCO 65.2
The same inheritance is mentioned by the Psalmist: “The Lord is the portion of mine inheritance.” 2Psalm 16:5. So here again we have a link to connect all God’s people with Abraham. Their hope is nothing else but the promise of god to him. EVCO 65.3
