17I beg you, friends, to be on your guard against people who, by disregarding the teaching which you received, cause divisions and create difficulties; dissociate yourselves from them.
18For such persons are not serving Christ, our Master, but are slaves to their own appetites; and, by their smooth words and flattery, they deceive simple-minded people.
19Everyone has heard of your ready obedience. It is true that I am very happy about you, but I want you to be well versed in all that is good, and innocent of all that is bad.
20And God, the giver of peace, will before long crush Satan under your feet. May the blessing of Jesus, our Lord, be with you.
