Why callest thou me good? According to the best authorities, the words in St. Matthew (Matthew 21:17) run thus: "Why askest thou me concerning that which is good? One there is who is good." The word "good" is the pivot on which our Lord's answer turns, both in St.
Matthew and here. The question is doubtless put to test the young ruler's faith. If, as may be supposed, the young man used the term, "good Master," as a mere conventional expression, it was not the proper epithet to apply to our Lord, who at once transfers the praise and the goodness to God, that he might teach us to do the same.
This ruler, by his mode of accosting our Lord, showed that he had not as yet a right faith in him—that he did not believe in his Godhead. Our Lord, therefore, desired to rouse him and lift him up to a higher faith.
He seems to say to him, "If you call me good, believe that I am God; for no one is good, intrinsically good, but God. God alone is essentially good, and wise, and powerful, and holy. It is from him that angels and men derive a few drops, or rather some faint adumbration, of his goodness.
There is none essentially, entirely, absolutely good but one, that is, God. Therefore seek after him, love him, imitate him. He alone can satisfy your longing desires, as in this life with his grace, so in the life to come with his glory; yea, with himself.
For in heaven he manifested himself as the supreme good, to be tasted and enjoyed by the blessed for ever."
