Romans 1:16
16For I am not ashamed of the Good News of Christ, because it is the power of God for salvation for everyone who believes, for the Jew first, and also for the Greek.
Paul is not ashamed of the gospel at Rome, the head of the world. Wesley: to the world it is folly and weakness, yet it is the power of God unto salvation to every one that believeth—the great and gloriously powerful means of saving all who accept salvation in God’s own way. Jew first, then Greek: the offer is ordered, not narrowed.
The passage carries a sincere, universal power: the gospel actually saves everyone who believes. “Everyone who believes” is not a code for a hidden list; it is the living condition of the power. Grace enables believing; it does not make the word a private instrument that never meant the neighbor who refuses. The Jew’s priority is historical honor, not a smaller mercy.
Calvin: Paul anticipates the world’s taunts and eulogizes the gospel so Rome will not find the cross contemptible. God puts forth his power to save in vocal preaching, not a secret revelation only. Yet he works not effectually in all, but only where the Spirit, the inward Teacher, illuminates the heart. The gospel is offered to all for their salvation; the power of it appears not everywhere.
“Everyone who believes” names those in whom the Spirit makes the word effectual. The offer is wide—Jew first, then Greek, no rank or nation fenced off. The salvation is God’s power, not the hearer’s contribution. Those who refuse find in the same gospel a proof of ruin; Christ offered as Savior will be Judge.
Key contrast Both glory in a gospel that is God’s power for salvation to Jew and Greek who believe, and neither is ashamed of the cross. Arminians find a sincere power unto all who will believe, faith the living condition of receiving it. Reformed interpreters hear the same wide offer, with effectual power only where the Spirit illuminates the heart—faith the fruit of that inward teaching, not an independent lever.
