Romans 8 (Week 3)
14 Paul calls the Spirit the arrabōn (a Semitic word that passed into Greek; GK 775) of our inheritance (see also 2 Co 1:22; 5:5). BDAG, 134, describe this entity as the “payment of part of a purchase price in advance, first installment, deposit, down payment, pledge.” The sense is clear enough. The Spirit in believers’ lives constitutes God’s “earnest money,” a kind of deposit from him by which he assures that he will give them their full inheritance. In v. 18 Paul speaks of the “riches of [God’s] glorious inheritance in the saints.” The Spirit is the down payment; the remaining riches will follow. A Spirit-filled life is a foretaste of what heaven will be like (cf. 5:18–21).
