¹⁷ Brothers and sisters, I ·ask [urge; encourage] you to look out for those who cause ·divisions [dissension] and who ·upset other people’s faith [create obstacles/stumbling blocks]. ·They [or Such things] are against the true teaching you learned, so stay away from them. ¹⁸ Such people are not serving our Lord Christ but are ·only doing what pleases themselves [serving their own appetites/^Lbellies]. They use ·fancy [smooth] talk and ·fine words [flattery] to ·fool [deceive] the ·minds of those who do not know about evil [^Lhearts of the innocent/naive]. ¹⁹ All the believers have heard ·that you obey [about your obedience/faithfulness], so I ·am very happy [rejoice] because of you. But I want you to be wise in what is good and innocent in what is evil.
