John Wesley, one of the great revivalists and founder of the Methodist movement, on the danger of revival:
I fear, wherever riches have increased . . . the essence of religion, the mind that was in Christ, has decreased in the same proportion.Therefore, I do not see how it is possible, inthe nature of things, for any revival of true religion to continue long.For religion must necessarily produce both industry and frugality; and these cannot but produce riches.But as riches increase, so will pride, anger, and love of the world in all its branches.How then is it possible that Methodism, that is, the religion of the heart, though it flourishes now as a green bay tree, should continue in this state?For the Methodists in every place grow diligent and frugal; consequently they increase in goods.Hence, they proportionably increase in pride, in the desire of the flesh, the desire of the eyes, and the pride of life.So, although the form of religion remains, the spirit is swiftly vanishing away.Is there no way to prevent this? this continual declension of pure religion?We ought not to forbid people to be diligent and frugal; we must exhort all Christians, to gain all they can, and to save all they can:this is, in effect, to grow rich!What way then, I ask again, can we take that our money may not sink us to the nethermost hell?There is one way, and there is no other under heaven.If those who gain all they can, and save all they can, will likewise give all they can, then the more they gain, the more they will grow in grace, and the more treasure they will lay up in heaven.
