We can glory in tribulations because our faith enables us to view them in such a way as to realize that, far from working against our hope, they actually promote it, and, indeed, further it. In other words the reaction of the Christian to tribulations is not an automatic one. It is not a case of ‘Come what may, I’m always happy’. He is enabled to glory in them as the result of the application of his faith. Because he is a man of faith he is able to do certain things. Trials and tribulations come, and at first he is troubled, he is made unhappy. But he does not stop at that; he proceeds to deal with them. How does he do this? The Apostle gives us the answer. ‘Not only so but we glory in tribulations also.” How? “Knowing”: it is because of something we know. – D. Martyn Lloyd-Jones, Romans, Volume 4, p. 66
