28 Then one of the scribes came, and having heard them reasoning together, perceiving that He had answered them well, asked Him, "Which is the first commandment of all?" 29 Jesus answered him, "The first of all the commandments is: 'Hear, O Israel, the Lord our God, the Lord is one. 30 And you shall love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength.' This is the first commandment. 31 And the second, like it, is this: 'You shall love your neighbor as yourself.' There is no other commandment greater than these." 32 So the scribe said to Him, "Well said, Teacher. You have spoken the truth, for there is one God, and there is no other but He. 33 And to love Him with all the heart, with all the understanding, with all the soul, and with all the strength, and to love one's neighbor as oneself, is more than all the whole burnt offerings and sacrifices." 34 Now when Jesus saw that he answered wisely, He said to him, "You are not far from the kingdom of God." But after that no one dared question Him.

Those who sincerely desire to be taught their duty, Christ will guide in judgment, and teach his way. He tells the scribe that the great commandment, which indeed includes all, is, that of loving God with all our hearts. Wherever this is the ruling principle in the soul, there is a disposition to every other duty. Loving God with all our heart, will engage us to every thing by which he will be pleased. The sacrifices only represented the atonements for men's transgressions of the moral law; they were of no power except as they expressed repentance and faith in the promised Saviour, and as they led to moral obedience. And because we have not thus loved God and man, but the very reverse, therefore we are condemned sinners; we need repentance, and we need mercy. Christ approved what the scribe said, and encouraged him. He stood fair for further advance; for this knowledge of the law leads to conviction of sin, to repentance, to discovery of our need of mercy, and understanding the way of justification by Christ.
