Verse explainer
Hope here isn't wishful thinking — it's an overflowing confidence God himself produces in believers through the Holy Spirit.
Now the God of hope fill you with all joy and peace in believing, that ye may abound in hope, through the power of the Holy Ghost.
BSBNow may the God of hope fill you with all joy and peace as you believe in Him, so that you may overflow with hope by the power of the Holy Spirit.
The plain meaning
Paul closes Romans 15 with a benediction, and the name he reaches for is striking: not "God of power" or "God of judgment" but "the God of hope." He has spent the chapter urging Jewish and Gentile believers in Rome to receive one another (vv. 7–12), quoting scripture to show that God's plan always included both. This blessing flows from that argument: the same God who kept his promises to the nations is the foundation on which their hope rests. The prayer has a shape — joy and peace come through believing, and that trust, sustained by the Holy Spirit, produces an overflowing hope. Paul is not describing an emotion believers work up; he is asking God to fill and flood them with it. The Spirit is the agent, not the believer's willpower. Notice too that "all joy and peace" lands on a church in tension — the strong and the weak, the Jew and the Gentile. Personal inward hope and communal harmony are, for Paul, the same gift from the same source.
The common misreading
What the commentators say
Henry observes that Paul deliberately addresses God as 'the God of hope' because every word in a prayer should be a plea — God is both the object of hope and its author, the one who builds it in us. He stresses that joy and peace are 'filling' in a way carnal joy never is, and that this fullness comes by believing: weak faith yields weak joy, stronger faith yields more. The abounding hope flows from the Spirit's power, not from the believer's effort, so all glory belongs to the Spirit.
Clarke reads 'the God of this hope' as pointing back to the fulfilled promises running through the chapter — God caused both Jews and Gentiles to hope, then fulfilled those promises punctually. Joy and peace come through believing in Christ, in whom all promises are 'yea and amen.' The abounding hope is God enlarging the believer's vision of salvation and then sealing that fulfillment on the heart by the Spirit's enabling power.
JFB see this as a concluding prayer over the whole epistle, not just a pious sign-off. Joy and peace are described as 'the native fruit of that faith which is the great theme of this epistle.' The abounding hope they have in mind is specifically the hope of the glory of God (Rom. 5:1–2). The Holy Spirit's role is definitive: it belongs to him, in the economy of redemption, to inspire believers with all gracious affections, including hope itself.
The word behind it
'Hope.' In ordinary Greek it could mean any expectation, good or bad. In Paul's usage it is a confident, assured expectation of what God has promised — closer to 'certainty about what is not yet seen' than to the English sense of a wish that might not come true. Naming God 'the God of elpis' anchors hope outside the believer's temperament: it is grounded in who God is and what he has promised, not in how optimistic one feels on a given day.
