For the LORD shall comfort Zion…Therefore the redeemed of the LORD shall return, and come with singing unto Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; and sorrow and mourning shall flee away. -Isaiah 51:3, 11

What can ye conceive of weeping and lamenting in the house where Jehovah dwelleth? It was a rule with one of the old monarchs that no one should come into his presence sad. In all our afflictions we may draw near to the Lord, but His presence should dispel our sorrow and sighing; for the children of Zion should be joyful in their King. If the Lord dwelleth in the midst of His people, there ought to be shoutings of joy. The presence of the King of Heaven is the heaven of their delight. Moreover, Zion enjoys her Monarch’s love, and therefore, He would have her comforted. We know not how dear to the heart of Christ His Church is, but we do know this: that for His Church He left His Father’s house and came down to earth, and was poor, that she, through His poverty, might be made rich. A man leaveth father and mother, and cleaveth to his wife, and they become one flesh; but what shall I say of the great mystery of this glorious Lover, who left His Father’s house, and did cleave unto His Church, and became one flesh with her that He might lift her up and set her upon His own throne, that she might reign with Him as the Bride, the Lamb’s Wife? Well may, therefore, the Lord desire His Church to be happy. Eternal love has fixed itself upon her. Eternal purposes cluster around her. Eternal power is sworn to protect her. Eternal faithfulness has guaranteed eternal life to all her citizens. Why should she not be comforted? I do not wonder that the text says the Lord will comfort the people whom He has thus favoured. ~ C.H. Spurgeon
