The God of peace will soon crush Satan under your feet.
The last letter to the Roman church with lots of greetings and encouragements. And a few warnings.
Immediate context is;
17 Now I urge you, brothers and sisters, keep your eye on those who cause dissensions and hindrances contrary to the teaching which you learned, and turn away from them. 18 For such people are slaves, not of our Lord Christ but of their own appetites; and by their smooth and flattering speech they deceive the hearts of the unsuspecting. 19 For the report of your obedience has reached everyone; therefore I am rejoicing over you, but I want you to be wise in what is good, and innocent in what is evil. 20 The God of peace will soon crush Satan under your feet.
How is the church involved in this final victory?
