28 And one of the scribes came, and hearing their argument together, and seeing that he had given them a good answer, put the question to him, Which law is the first of all? 29 Jesus said in answer, The first is, Give ear, O Israel: The Lord our God is one Lord; 30 And you are to have love for the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength. 31 The second is this, Have love for your neighbour as for yourself. There is no other law greater than these. 32 And the scribe said to him, Truly, Master, you have well said that he is one, and there is no other but he:

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.
