do good - like God Himself (Psa 119:68; Act 14:17) and Christ (Act 10:38). Tittmann translates, “to do,” or “act well”; as the Greek for “to be beneficent” is a distinct word, agathopoiein.
rich in good works - so “rich in faith,” which produces good works (Jam 2:5). Contrasted with “rich in this world,” 1Ti 6:17. Literally, it is “rich in honorable (right) works.” Greek, “kalois,” “ergois,” are works good or right in themselves: “agathois,” good to another.
ready to distribute - free givers [Alford]; the heart not cleaving to possessions, but ready to impart to others.
willing to communicate - ready contributors [Alford]: liberal in admitting others to share our goods in common with ourselves (Gal 6:6; Heb 13:16).
