The Scribes: Which Is the First Commandment of All?

And one of the scribes came, and heard them questioning together, and knowing that he had answered them well, asked him, What commandment is the first of all? Jesus answered, The first is, Hear, O Israel; The Lord our God, the Lord is one: and thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength. The second is this, Thou shalt love thy neighbor as thyself. There is none other commandment greater than these. And the scribe said unto him, Of a truth, Teacher, thou hast well said that he is one; and there is none other but he: and to love him with all the heart, and with all the understanding, and with all the strength, and to love his neighbor as himself, is much more than all whole burnt-offerings and sacrifices. And when Jesus saw that he answered discreetly, he said unto him, Thou art not far from the kingdom of God. And no man after that durst ask him any question.

Mark 12:28-34

Jesus told him, "I am the way, the truth, and the life. No one can come to the Father except through me." (John 14:6)
