I urge you, brothers and sisters, to watch out for those who cause divisions and put obstacles in your way that are contrary to the teaching you have learned. Keep away from them. For such people are not serving our Lord Christ, but their own appetites. By smooth talk and flattery they deceive the minds of naive people.
Romans 16:17-18//

There are certain types of people within our own ranks that we are instructed to stay away from. Lord, grant me discernment and wisdom to identify these people, and implement appropriate boundaries.
