It was not what he had done, but what he had left undone, that wakened fears and forebodings in this young ruler’s mind. The outward observance of the ten commandments was right and well in its own way and place; but the failure to obey, from the heart, the first and great command was the condemnation that rested upon him. He probably knew this, in some measure. He was not confidently certain of eternal life; and therefore he came to the Great Teacher, hoping to elicit from Him an answer that would quiet his conscience, and allow him to repose upon his morality while he continued to love this world supremely. The Great Teacher pierced him with an arrow. He said to him, “If them wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven: and come and follow me.” This direction showed him what he lacked.

This is the reason that the sin of omission is as punishable as the sin of commission. In either case alike, the man is off the line of rectitude. Hence, in the final day, man will be condemned for what he lacks, for what he comes short of, in moral character. Want of conformity to the Divine law as really conflicts with the Divine law, as an overt
