It only remains to observe the constancy of Christ’s intercession. He is continually employed in this work. His oblation was the work of comparatively a short period, but his intercession never ceases.
Human benevolence may become languid, may intermit for a time, or may finally die away altogether. But not so the benevolence which prompts the petitions of our Advocate. He can never become languid from ignorance of his people’s wants, for he is omniscient; nor from want of affection, for his love is abiding; nor from want of merit, for his sacrifice is of unfailing virtue; nor from fatigue, for he is the almighty and immutable God. Nothing can ever occasion a suspension. A moment’s intermission would prove fatal to the eternal interests of all the elect. But, while attending to the case of one, he has no need to suspend attention to that of another. Innumerable as are his applicants, he attends to the wants of each as if there were not another that needed his care. Multiplicity cannot bewilder, variety cannot divide, importance cannot oppress his thoughts. To him the care of millions is no burden. Ten thousand claims meet with the same attention as if there were but one. His understanding, his love, his merit, his power, are all infinite; and we must beware of measuring him by the low standard of our own limited capacities.
Nor can his intercession ever come to an end. There will be need for it forever. So long as his people sin, he will plead for pardon; so long as they are tempted, he will procure them strength to resist; so long as they continue to perform services, he will continue to give them acceptance; so long as they are in the wilderness, he will procure them guidance and safety; nay, so long as the blessings of heaven are enjoyed, will he plead his merits as the ground on which they are bestowed. Through eternity will he continue to plead on behalf of his people. Never shall they cease to be the objects of his care; never shall their names be erased from his breast; never shall their cause be taken from his lips; never shall the odour-breathing censer drop from his hand; nor shall his blessed merits ever cease to rise up in a cloud of fragrant incense before the Lord. He ever liveth to make intercession for them.
