Then we have the reason of both these significant observances laid down.--"And thou shalt show thy son in that day, saying, This is done _because of that_ which the Lord did unto me when I came forth out of Egypt." And again, "It shall be, when thy son asketh thee in time to come, saying, What is this? that thou shalt say unto him, By strength of hand the Lord brought us out from Egypt, from the house of bondage. And it came to pass, when Pharaoh would hardly let us go, that the Lord slew all the first-born in the land of Egypt, both the first-born of man and the first-born of beast; _therefore_ I sacrifice to the Lord all that openeth the matrix, being males; but all the first-born of my children I redeem." The more fully we enter, by the power of the Spirit of God, into the redemption which is in Christ Jesus, the more decided will be our separation, and the more whole-hearted will be our devotedness. The effort to produce either the one or the other, until redemption is known, will prove the most hopeless labor possible. All our doings must be "because of that which the Lord hath done," and not in order to get anything from Him. Efforts after life and peace prove that we are, as yet, strangers to the power of the blood; whereas the pure fruits of an experienced redemption are to the praise of Him who has redeemed us. "For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: not of works, lest any man should boast. For we are His workmanship, created in Christ Jesus unto good works, which God hath before prepared that we should walk in them." (Eph. ii. 8-10.) God has already prepared a path of good works for us to walk in; and He, by grace, prepares us to walk therein. It is only as saved that we can walk in such a path. Were it otherwise, we might boast; but seeing that we ourselves are as much God's workmanship as the path in which we walk, there is no room whatever for boasting.
