His sermons are entirely readable. This is an abberation. Some of his sermons make perfect sense, like this one:
O thou poor distressed soul! whoever thou art, consider that Christ mentions thy very case when he calls to them who labor and are heavy laden! How he repeatedly promises you rest if you come to him! In the 28th verse he says, "I will give you rest." And in the 29th verse, "Ye shall find rest to your souls." This is what you want. This is the thing you have been so long in vain seeking after. O how sweet would rest be to you, if you could but obtain it! Come to Christ, and you shall obtain it. And hear how Christ, to encourage you, represents himself as a lamb! He tells you, that he is meek and lowly in heart, and are you afraid to come to such a one! And again, Rev. 3:20. "Behold, I stand at the door and knock: if any man hear my voice, and open the door, I will come in to him, and I will sup with him and he with me." Christ condescends not only to call you to him, but he comes to you; he comes to your door, and there knocks. He might send an officer and seize you as a rebel and vile malefactor, but instead of that, he comes and knocks at your door, and seeks that you would receive him into your house, as your Friend and Savior. And he not only knocks at your door, but he stands there waiting, while you are backward and unwilling. And not only so, but he makes promises what he will do for you, if you will admit him, what privileges he will admit you to; he will sup with you, and you with him.
See what clarity of thought went into that snippet? And then, when he attacks Arminianism, its like he's writing in tounges.
