Verses 17 and 18 stood out to me today, 17 I urge you, brothers, 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. 18 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. This is why it is so important to spend your own time in God’s word, so that you know the accuracy of what you are being taught from sermons and books. If we rely solely on a person’s opinion, without checking the validity of their teaching, we risk the potential for being misled into inaccurate information.
