Romans 16:17-20
16:17 Now I urge you, brothers and sisters, to watch out for those who create dissensions and obstacles contrary to the teaching that you learned. Avoid them!
16:18 For these are the kind who do not serve our Lord Christ, but their own appetites. By their smooth talk and flattery they deceive the minds of the naive.
16:19 Your obedience is known to all and thus I rejoice over you. But I want you to be wise in what is good and innocent in what is evil.
16:20 The God of peace will quickly crush Satan under your feet. The grace of our Lord Jesus be with you.
