I. MEDIATION CONCERNS ITSELF WITH THE INTERESTS OF BOTH PARTIES. Moses had at heart the honor of God - the maintenance of his just rule, while he also identified himself with the well-being of the Hebrews. If there be, on the part of the mediator, a leaning to the interests of the one party rather than the other, his office will fail. One party or both will reject him. His mission proceeds on the ground that there is an advantage common to both to be obtained by reconciliation. There is a point where God's interests and man's touch and blend. The business is to find that point, and to persuade both parties there to meet.

II. MEDIATION IS ITSELF A FRUIT OF DIVINE MERCY. The disposition in the heart of Moses to intercede was a disposition implanted by God, and all the energy with which he pursued this mission was energy sustained from heaven. Further, the willingness, on the part of God, to allow any suit on behalf of rebels, was an act of pure mercy. It is no less absurd than profane to speak of man, the mediator, as showing more benevolence than God. The whole arrangement is one of purest kindness, and Moses was richly blest in his generous undertaking.

III. MEDIATION REQUIRES THE MOST COMPLETE SELF-SACRIFICE. For forty days and forty nights Moses was prostrate before the Lord. Personal needs, personal interests, personal honor, were all forgotten. Here was the completest devotion of himself to this cause. There is a profound mystery in this number of forty. It is not a natural cycle. Like the number seven, it is sacred to religion. For forty days and nights Moses waited before God, undergoing spiritual receptiveness for the revelation of his will. For forty years the Hebrews dwelt in the wilderness. For forty days Elijah tarried in Horeb. For forty days Jesus endured the temptations of the desert. For forty days he abode with men subsequent to his resurrection. All that human nature could endure, Moses endured to obtain pardon for Israel. For if pardon be too cheaply bought, it is not valued. Only in the lurid light of sin's curse do we see the glory of forgiveness.

IV. MEDIATION ACKNOWLEDGES SIN TO THE FULL. There is no extenuation of the deed, no paring down its dimensions, no cloaking any part of its baseness, no endeavors to put other colors on it than its own. It is because sin is so malignant and so ruinous that it is so desirable to rescue the sinner from its awful spell. It is because it is so dishonoring to God that it is worth while, at any price, to remove it from his universe. The anger of Jehovah is no mere passing or capricious feeling. It is sentiment arising out of the most righteous principle. Such anger against sin is essential to the Godhead. We need not be afraid of the introduction of anthropomorphic conceptions. The longer Moses remained prostrate before God, the clearer came into view Israel's sin in the light of the Divine purity.

V. MEDIATION INCLUDES THE LARGEST REPARATION. The mission of Moses as mediator had a part manward as well as Godward. The whole work was not done upon his knees. With both his hands he brake and burnt the graven image, dishonored the deity they had fashioned, reduced it to powdered dust. This would expose the impotence of the idol, the vanity of the idol system, and the insane folly of presenting to such a molten image Divine honors. Nor was this all. The fine dust that remained after the burning was cast into the brook, so that they were compelled to drink it in the exigency of their thirst. St. Paul tells us that the rock from which this stream flowed symbolized Christ; hence we see, in a figure, how the living stream from him, the Fount, bears away our sin into oblivion. Repentance upon our part is not thorough, nor sincere, unless we make whatever reparation is within our reach,

VI. MEDIATION EMBRACES VERBAL INTERCESSION. The final outcome of mediation is prayer. "Father, forgive them!" said the dying Savior. "He ever liveth to intercede."

1. Moses pleads God's proprietorship in this recreant people. "They are thine inheritance." "The Lord's portion is his people." From them he shall obtain more satisfaction than from planets and stars and suns.

2. God's self-consistency is an argument in prayer, he had already redeemed them from Egyptian bondage. He had taken great pains with them hitherto, and had expended great power on their behalf. And he had not done this in ignorance. The latent evil in their hearts he had perceived. The future of their lives he had foreseen. Hence it would be consistent with his past favors to dispense fresh mercy.

3. God's covenant and promises are proper arguments in prayer. He loves to be reminded of his engagements, because this remembrance deepens our sense of his faithfulness. He had engaged to bring this people to the land of promise, not for their sakes, however obedient they might be, but for their fathers' sakes. Hence their rebelliousness did not vitiate the original engagement; and although individuals might justly be destroyed - yea, that whole generation - still the posterity of Abraham must eventually enter the land.

4. The reputation and credit of God form also staple arguments in prayer for others. The natural effect produced on men's minds by God's dealings must be taken into account. Our God is not indifferent to the homage and praise of men. It is to him a great delight to receive the incense of heartfelt love. His reputation in his universe is a very precious thing, and it becomes us on all occasions to guard it well. He has formed us into a people for this very purpose, "that we should show forth his praise."

VII. HUMAN MEDIATION, IF EARNEST AND PERSEVERING, SUCCEEDS. "The Lord hearkened unto me at that time also." Here is great encouragement for our intercession now! Abraham did not cease to gain successes for Sodom until he ceased to pray; and had he continued, possibly the city might have been spared. What genuine and honest intercession has ever failed? "The fervent prayer of a righteous man availeth much." Every instance of successful intercession recorded in history is a cordial to revive our drooping faith. Is not God even now waiting to hear human intercession, that he may do great things for his Church? "Give him no rest, till he make Jerusalem a praise in the earth." - D.

II. HE ASSURES THEM OF VICTORY, BY THE PRESENCE OF GOD WITH THEM, NOTWITHSTANDING THE STRENGTH OF THE ENEMY (ver. 3). Observe, "He shall destroy them," and then, "thou shalt drive them out." Thou canst not drive them out unless He destroy them, and bring them down; but He will not destroy them, and bring them down, unless thou set thyself in good earnest to drive them out. We must do our endeavour in dependence upon God's grace; and we shall have that grace, if we do our endeavour.

III. HE CAUTIONS THEM NOT TO ENTERTAIN THE LEAST THOUGHT OF THEIR OWN RIGHTEOUSNESS, AS IF THAT HAD PROCURED THEM THIS FAVOUR AT GOD'S HAND (vers. 4-6). In Christ we have both righteousness and strength; in Him, therefore, we must glory, and not in ourselves, or any sufficiency of our own.

IV. HE INTIMATES TO THEM THE TRUE REASONS WHY GOD WOULD TAKE THIS GOOD LAND OUT OF THE HANDS OF THE CANAANITES AND SETTLE IT UPON ISRAEL.

1. He will be honoured in the destruction of idolaters (vers. 4, 5).

2. He will be honoured in the performance of His promise to those that are in covenant with Him (ver. 5).
