I. The God of all peace sends peace to all His creatures. As He sends the light, as He sends the air, so He sends peace. And in token that He desires peace for us, He has set apart and empowered and accredited certain men to deliver it. The fact that there is a ministry at this moment is a proof that God means peace for us. But it all depends upon one thing upon adaptation. The peace is to the house, but the question whether the house or any one in it can have the peace turns upon the point of adaptation. "If the house is worthy" that is, if there be a fitness or adaptation in the house to receive then the peace will enter. But if the house be not worthy, then the peace will not enter, but it will rebound, it will find no correspondence in the thing which it seeks to light upon.
II. Consider what this peace means. (1) It is peace with God the peace which a man feels when his sins are forgiven, and he knows that God is no longer his enemy, but his Friend. (2) It is peace through the blood of Jesus Christ. It is the peace which has no fear in it. It is the peace which gives a man strength to live and confidence to die. (3) It is a peace within between a man and himself. His conscience, being sprinkled, is at peace; and the past does not now awake up to torment him, and the man is one, which he was not before; his heart is single, and singleness of heart is peace. (4) It is peace with the whole world. The peace with God made a peace within; and the peace within makes peace without. He is too humble to quarrel, and too little in his own eyes to see wrong in other men. He contemplates God till he grows like Him; as God is, so is he in this world; and God is love.
