Paul loved all the brethren and was acquainted with what many were doing. He was rich in friendships. And this is why he remembers so many, even if only by name (in a few cases). Men and women alike helped him greatly. Where praise was due, Paul never failed to give it. Wouldn’t that be a nice way for us to act with other believers?
V.17-18 Paul was not trying to win popularity by flattering everyone. He has some sharp things to say about those who were causing divisions making denominations. Today many believers are tolerant about those who cause divisions and offenses contrary to the doctrine they have learned. Notice what should be done to these people.
V.25-27 Beautiful end to this mighty Epistle. May we have grace from God to live according to its words. Then we shall walk in the joy of the blessings of this final expression of praise to God.
