We have somewhere heard of a chemist who was lecturing before his class. A number of rags of varied hue lay before him, and by means of strong chemicals he was changing their colors into whiteness. Presently he paused, and holding up a piece of Turkey red, he remarked, "Ah! now we shall have some trouble, for of all colors this is the hardest to extract." Again and again he dipped it into the strong solution, but with little effect; then cast it aside, saying, "It must either remain as it is, or else lie in the solution till its very fibres are destroyed." But the blood of Christ has power to extract even scarlet stains. "Though your sins be as scarlet, they shall be white as snow; though they be red like crimson, they shall be as wool." Then "why art thou cast down, O my soul?" for "the righteousness of God, which is by faith of Jesus Christ unto all them that believe," is "for the remission of sins that are past," as well as for the constantly recurring sins of the present. Shall we, then, never think of our past sins? Yes; think of them as the mariner thinks of dangers past, and as the redeemed in glory think of past tribulations. "He maketh the storm a calm, so that the waves thereof are still. Then are they glad because they be quiet; so he bringeth them unto their desired haven." Yes; think of them with gratitude to God for deliverance, and let this be your song as you press on: "He sent from above, he took me; he drew me out of many waters: he delivered me from my strong enemy, and from them that hated me; for they were too strong for me." "When I said, My foot slippeth, thy mercy, O Lord, held me up." "The Lord is my rock, and my fortress, and my deliverer; the God of my rock: in him will I trust; he is my shield, and the horn of my salvation, my high tower, and my refuge, my Saviour." "For who is a God, save the Lord? and who is a rock, save our God? Therefore I will give thanks unto thee, O Lord, among the heathen, and I will sing praises unto thy name." Think of them, also, with humility and self-distrust, and let this be your constant prayer: "Hold up my goings in thy paths, that my footsteps slip not." "Keep me as the apple of the eye; hide me under the shadow of thy wings." But oh do not carry the memory of past sins as a weight to drag your soul down to the dust! If the Lord has forgiven and forgotten them, why not rejoice in this wonderful token of his love toward you? Casting aside every weight, you may thus rise to the enjoyment of "a present heaven."
