John 3:30 - Wesley's Explanatory Notes

He must increase, but I must decrease — So 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, amidst 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.
