Lord, now lettest thou thy servant depart in peace… – Luke 2:29

No man can depart in peace who has not lived in peace; but he who has attained peace in life shall possess peace in death, and an eternity of peace after death. “Being justified by faith we have peace with God through our Lord Jesus Christ.” Jesus has bequeathed us peace, saying, “Peace I leave with you, My peace I give unto you.” “For He is our peace,” and “the fruit of the Spirit is peace.” We are reconciled unto God by the death of His Son. Whatever peace flowed in the heart of Simeon, I am sure it was not of a diviner nature than that which dwells in the bosom of every true believer. If sin be pardoned, the quarrel is ended; if the atonement is made, then is peace established, a peace covenanted to endure for ever. We are now led in the paths of peace; we walk the King’s highway, of which it is written, “no lion shall be there;” we are led beside the still waters and made to lie down in green pastures. We feel no slavish fear of God, though He be “a consuming fire” even to us; we tremble no longer to approach into His presence, who deigns to be our Father. The precious blood upon the mercy-seat has made it a safe place for us to resort at all times; boldness has taken the place of trembling. The throne of God is our rejoicing, though once it was our terror.

“Once ’twas a seat of dreadful wrath,
And shot devouring flame;
Our God appear’d ‘consuming fire,’
And vengeance was His name.”

Therefore, brethren, having peace with God, we may be sure that we shall “depart in peace.” We need not fear that the God of all consolation, who has already enriched us in communion with Himself, and peace in Christ Jesus, will desert us at the last. He will help us to sing a sweet swan-song, and our tabernacle shall be gently taken down, to be rebuilt more enduringly in the fair country beyond Jordan. ~ C.H. Spurgeon
