MOAB did not love David, as Ahimaaz did, and could not understand what made the young man so eager to carry the tidings. Doubtless Ahimaaz and Cushi entirely misinterpreted the heart of David, and thought that he would be glad to hear that the rebellion was stamped out, and Absalom was dead. And it was because of the pleasure which he thought to give his king that the swift‑footed son of Zadok pleaded for permission to run. What though there would be no reward, or that it would fall to the lot of Cushi, who had already started at Joab's command ‑‑ that mattered not, the love of David constrained him.
How often that question of reward is thrown at the servants of God! It is one of the favorite taunts of the world; as Satan said of Job, that we do as we do because we are paid. "Doth Job serve God for nought?" And nothing so startles men as disinterested service. They cannot account for it; but it wins their respect. "Reward or no reward; recompense or none; smiles or tears, come what may, let me run." That is the spirit that becomes a Christian, and convinces the world. "The love, of Christ constraineth us."
Ahimaaz outran Cushi. The one was a volunteer for love's dear sake; the other, a bond‑servant, doing as he was told. Love lent wings to his feet, and speeding past his fellow bore him first into David's presence. So God's will is done in heaven: "The cherubim ran and returned like a flash of lighting." So God's will is done on earth: "They departed quickly from the tomb with fear and great joy, and ran to bring his disciples word. And behold, Jesus met them, saying, All hail!"
