Acts 26:18 records six aspects of the heavenly commission from the Lord Jesus to Paul. The last is that we receive an inheritance. As with all five prior aspects, the consumma-tion of the inheritance is with New Jerusalem.
This inheritance comes to us in three stages—in this age, in the age that begins with the Lord’s second coming, and in eternity in New Jerusalem.
The New Testament primarily speaks of the inheritance in the kingdom age and in eternity. Nevertheless, Ephesians 1:14 says that the Spirit “is the pledge of our inheritance.” This pledge is a guarantee. It is also a sample, giving us a present taste of the coming inheritance. The Spirit Himself, as our realization of the Triune God, is the sample, indicating that the Triune God is the fullness of our inheritance.
Also, Galatians 3:14 speaks of our receiving the blessing of Abraham, which is the promised Spirit. The promise is of God (v. 16), it is also God’s covenant (v. 17), and it is our inheritance (v. 18). This is the Spirit flowing as the river of life in New Jerusalem.
In Revelation 21:7 the Lord tells us, “he who overcomes will inherit these things.” This is in the context of the Lord describing Himself and describing New Jerusalem. Hence, the Lord Jesus Christ as the reality of everything in New Jerusalem and as the embodiment of the Triune God is our inheritance.
An overall definition:* This inheritance is the Triune God Himself with all He has, all He has done, and all He will do for His redeemed people. The Triune God is embodied in the all-inclusive Christ (Col. 2:9), who is the portion allotted to the saints as their inheritance (Col. 1:12).
Ultimately this inheritance is the Triune God in New Jerusalem allotted to us.
