This was more than just a ‘general’ letter for Paul. He wanted the church to know what and how he was doing, as well as Tychicus “a beloved brother and faithful minister in the Lord,” who would “make all things known” to them (v. 21). Paul seems to always have at least one helper with him. Tychicus was also sent to provide the church some comfort to their hearts (v. 22 cf. II Cor. 1:3-7). Comfort is seen in peace, love, and faith, “from God the Father and the Lord Jesus Christ.” (v. 23 cf. I Cor. 13:13) We sometimes see the word ‘sincerely’ at the end of a letter, and perhaps consider it a mere formality. However, for Paul it is intentional. Some may profess Christ or Christianity, but without grace or love, but eventually one’s true colours will be seen. Paul hoped for the good.
