[1] In nature there is hardly a stone that is not capable of crystallising into something purer and brighter than its normal state. Coal, by a slightly different arrangement of its particles, is capable of becoming the radiant diamond. The slag cast out from the furnace as useless waste forms into globular masses of radiating crystals. From tar and pitch the loveliest colours are now manufactured. The very mud of the road, trampled under foot as the type of all impurity, can be changed by chemical art into metals and gems of surpassing beauty; and so the most unpromising materials, the most worthless moral rubbish that man cast out and despise, may be converted by the Divine alchemy into the gold of the sanctuary, and made jewels fit for the mediatorial crown of the Redeemer. Let the case of Mary Magdalene, of John Newton, of John Bunyan, of thousands more, encourage those who are still in the gall of bitterness and in the bond of iniquity. Seek to be subjected to the same purifying process; lay yourselves open to the same spiritual influences; yield yourselves up into the hands of the Spirit to become His finished and exquisite workmanship; seek diligently a saving and sanctifying union with Christ by faith, and He will perfect that which concerneth you, and lay your stones with fair colours (Ps. lxviii. 13).--_Macmillan._ COMFORT FOR THE DESPONDING. i. 18. _Come now, and let us reason together, saith the Lord; Though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool._
