John Wesley on Ecclesiastes 1:4

Passeth - Men continue but for one, and that a short age, and then they leave all their possessions, and therefore they cannot be happy here, because happiness must needs be unchangeable and eternal; or else the certain knowledge of the approaching loss of all these things will rob a man of solid contentment in them. Abideth - Through all successive generations of men; and therefore man is more mutable than the very earth upon which he stands, and which, together with all the comforts which he enjoyed in it, he leaves behind to be possessed by others.
