Read: John 1:14-18
Out of his fullness we have all received grace in place of grace already given. For the law was given through Moses; grace and truth came through Jesus Christ. No one has ever seen God, but the one and only Son, who is himself God and is in closest relationship with the Father, has made him known. (John 1:16-18)
Notice the reappearance in verse 17 of the words grace and truth, and the contrast which John draws between them and the Law and Moses. The Law makes demands. It is hard, cold, unyielding, without mercy. The symbol of it today is the IRS — the Tax Man. If we do not give up what the law requires we are subject to penalty: Do this and thou shalt live, says the IRS. John says that the Law was given by Moses. Moses did not originate it, but he gave it. Moses may disappear, but the Law remains — cold, unyielding, demanding, without mercy.
