One great cause of our frequent conflicts is, that we have a secret desire to be rich—and it is the Lord’s design to make us poor. We want to gain an ability of doing something—and He suits his dispensations, to convince us that we can do nothing. We want a stock of power in ourselves—and He would have us absolutely dependent upon Him. So far as we are content to be weak—that His power may be magnified in us—so far we shall make our enemies know that we are strong, though we ourselves shall never be directly sensible that we are so. Only by comparing what we are, with the opposition we stand against—we may come to a comfortable conclusion, that the Lord works mightily in us. Psa. 41:11.
