Matthew 5:17

Think not that I am come to destroy the law - Do not imagine that I am come to violate the law καταλυσαι , from κατα , and λυω , I loose, violate, or dissolve - I am not come to make the law of none effect - to dissolve the connection which subsists between its several parts, or the obligation men are under to have their lives regulated by its moral precepts; nor am I come to dissolve the connecting reference it has to the good things promised. But I am come, πληρωσαι , to complete - to perfect its connection and reference, to accomplish every thing shadowed forth in the Mosaic ritual, to fill up its great design; and to give grace to all my followers, πληρωσαι , to fill up, or complete, every moral duty. In a word, Christ completed the law:

1st. In itself, it was only the shadow, the typical representation, of good things to come; and he added to it that which was necessary to make it perfect, His Own Sacrifice, without which it could neither satisfy God, nor sanctify men.
