Romans 16:17-20
17 Now I urge you, brothers, to watch out for those who cause dissensions and obstacles contrary to the doctrine you have learned. Avoid them, 18 for such people do not serve our Lord Christ but their own appetites. They deceive the hearts of the unsuspecting with smooth talk and flattering words.
19 The report of your obedience has reached everyone. Therefore I rejoice over you. But I want you to be wise about what is good, yet innocent about what is evil. 20 The God of peace will soon crush Satan under your feet. The grace of our Lord Jesus be with you.
1 Corinthians 16:13-18
13 Be alert, stand firm in the faith, act like a man, be strong. 14 Your every action must be done with love.
15 Brothers, you know the household of Stephanas: They are the firstfruits of Achaia and have devoted themselves to serving the saints. I urge you 16 also to submit to such people, and to everyone who works and labors with them. 17 I am pleased to have Stephanas, Fortunatus, and Achaicus present, because these men have made up for your absence. 18 For they have refreshed my spirit and yours. Therefore recognize such people.
