Psalms 102:12

Many exceedingly great and precious comforts are here thought of, and mustered up, to balance the foregoing complaints; for unto the upright there arises light in the darkness, so that, though they are cast down, they are not in despair. It is bad with the psalmist himself, bad with the people of God; but he has many considerations to revive himself with. I. We are dying creatures, and our interests and comforts are dying, but God is an everliving everlasting God (Psa 102:12): "My days are like a shadow; there is no remedy; night is coming upon me; but, thou, O Lord! shalt endure for ever. Our life is transient, but thine is permanent; our friends die, but thou our God diest not; what threatened us cannot touch thee; our names will be written in the dust and buried in oblivion, but thy remembrance shall be unto all generations; to the end of time, nay, to eternity, thou shalt be known and honoured." A good man loves God better than himself, and therefore can balance his own sorrow and death with the pleasing thought of the unchangeable blessedness of the Eternal Mind. God endures for ever, his church's faithful patron and protector; and, his honour and perpetual remembrance being very much bound up in her interests, we may be confident that they shall not be neglected. II.
