"Who should be the greatest?" was on the disciples' minds as they walked along the way. In this sermon about disputes, Matthew Henry preaches on Mark 9:33. The topics include disputes about superiority, not judging others, edifying communication, and being accountable. The reason to avoid disputes is that "It is against the law of humility to covet to be great in this world, and against the law of love to strive who shall be greatest." Matthew Henry states that there remains "corruption in the hearts even of good people; and shows that pride, ambition, and affectation of worldly honor, are sins that do most easily beset even Christ's own disciples." He exhorts readers to humbly contend who shall be the best, who shall be most humble, and stoop lowest, for the good of others; and who shall labor most for the common welfare.
