John 3:30,31

He must increase And appear continually more and more glorious, like the growing moon; but I must decrease Must gradually wane and decline, till I disappear: for the end of my ministry is now, in a great measure, answered, and therefore I quickly expect to be dismissed from it. He that cometh from above is above all As if he had said, It is fit he should increase, while I decrease; for he is a person of infinitely greater dignity than I am, possesses far more knowledge of the divine will, and the discoveries which he makes thereof as far transcend mine as heaven exceeds earth. Thus John speaks of Christ's increase and his own decrease, not only as what was necessary and unavoidable, and that which could not be prevented, and therefore must be borne; but as highly just and agreeable to him: and he is entirely satisfied with it, nay, and rejoices in it. Thus they who are now like John, burning and shining lights, must, (if not suddenly eclipsed,) like him, gradually decrease, while others are increasing about them; as they in their turns grew up amid the decays of the former generation. Let us know how to set as well as how to rise; and let it comfort our declining days, to trace, in those who are likely to succeed us in our work, the openings of yet greater usefulness. But let us especially rejoice to observe the glory of Christ increasing, and eclipsing the lustre of all other glory, as the increasing light of the morning causes the glory of the morning star to decline, and at last entirely to disappear. And, if our diminution and abasement may but in the least contribute to the advancement of his name and honour, let us cheerfully submit to it, and be content to be any thing, yea, to be nothing, so that Christ may be all.
