Wesley is great! His love for his Lord and his zeal for the lost are examples to us all. He rode around 100,000 miles up and down Britain to preach the Gospel, and was excluded from many Anglican churches for preaching free grace and salvation by faith.
I love the story (not sure if it's true) of when he preached at a posh church in Oxford where several retired Bishops, wealthy clergymen and luminaries of the University were in attendance. He selected for his text Matthew 23:33. 'Serpents, brood of vipers! How can you escape the condemnation of hell?' According to the account I read, he 'flayed the congregation mercilessly and they gnashed their teeth at him.' At the close of the service, a wealthy lady came up to him and said, "Mr Wesley, how dare you preach such things to us? If you speak to us like that, what would you say to the fish porters at Billingsgate?" "Ah, Madam," he replied, "To them I would have preached, 'Behold the Lamb of God who takes away the sin of the world.'"
So I'm a big fan. Not quite so keen on all his theology, but hey! No one's perfect.
