At first blush, this statement may seem out of place. Paul has been exhorting mature Christians to restore the fallen with the meekness of self-examination and a call to personal duty. Verse 6 is a particular application of “bear one another’s burdens” as we “fulfill the law of Christ” (Gal. 6:2). It stands in opposition to “let us not be…envying one another” (Gal. 5:26). Where envy exists, there is self-seeking, confusion, and every evil thing (Jas. 3:16). Lange says of today’s verse, “this is the very strongest antithesis to envying” (Commentary on Galatians, 150). Instead of “grudgingly withholding” from the teacher of God’s word, the student is to “share in all good things” with the teacher. Share (koinoneo) is the verb form of “fellowship.” The sharing of “all good things” is foundational for the Lord’s command, “that those who preach the gospel should live from the gospel” (1 Cor. 9:14). We ought to share in the material support of those who teach God’s word. No ill-will should form toward the teacher of God’s word in the heart of the student. Just the opposite. The fellowship of temporal support between student and teacher is the practical application of our charge, namely, “through love serve one another” (Gal. 5:13).
