"Oh! The Word holds forth a way full of comfort and peace to the people of God even in this world, you may live happy that lives in the midst of all the storms and tempests in the world, there is an Ark that you may come into, and no men in the world may live such comfortable, cheerful, and contented lives as the Saints of God: Oh that we had learned this Lesson: I have been many sermons about this Lesson of contentment, but I am afraid that you will be longer in learning of it, than I have been preaching of it; it is a harder thing to learn than it is to speak or preach of it. (I remember) I have read of one man reading of that place in the 39, Psalm, I will take heed that I offend not with my tongue: faith he, I have been this 38 years learning this lesson, and have not learned it thoroughly. The truth is, there are many (I am afraid) that have been professors near 38 years, have hardly learned this lesson; it were a good lesson for young professors to begin to learn this betimes. But now, this lesson of Christian contentment, it is as hard, and perhaps you may be many years in learning it: I am afraid there be some Christians that have not yet learned, not to offend grossly with their tongues: The Scripture faith, all a mans religion is vain, if he cannot bridle his tongue; therefore, those that make any profession of godliness, one would think they should quickly learn this lesson, such a lesson that except learned it makes all their religion vain: But for this lesson of Christian contentment it may take up more time to learn, and there's many that are learning it all the days of their lives, and yet are not proficient, but God forbid that it should be said of any of us, concerning this Lesson, as the apostle faith of widows, in Timothy; That they were ever learning, and never came to the truth. O let us not be ever learning this lesson of contentment, and yet never come to have skill in it. You would think it much if you had used the Sea twenty years, and yet to have attained no skill in your art of navigation, you will say, I have used the sea twenty or thirty years, and I hope I may know by this time what belongs to the sea; O that you would but say so in respect of the art of Christianity! When there is anything that's spoken concerning the duty of a Christian, O that Christians could but say, I have been a Christian thus long, and I hope I am not to seek in such a thing that is so necessary for a Christian; here is a necessary Lesson for a Christian, that Paul said, He had learned in all estates therewith to be content. O be not content with yourselves till you have learned this Lesson of Christian contentment!"
