"...Christian contentment means that my satisfaction is independent of my circumstances.
...for Paul, contentment was rooted not in self-sufficiency but in Christ’s sufficiency (Phil. 4:13). Paul said that he could do all things—both being abased and abounding—in Christ...
...contentment is something we have to learn. And here is the crux of the matter: to learn it, we must enroll in the divine school in which we are instructed by biblical teaching and providential experience.
...Christian contentment, therefore, is the direct fruit of having no higher ambition than to belong to the Lord and to be totally at His disposal in the place He appoints, at the time He chooses, with the provision He is pleased to make.
...If I insist on knowing exactly what God is doing and what He plans to do with my future, if I demand to understand His ways with me in the past, I can never be content until I am equal with God.
...In our Augustinian tradition, it has often been said that the first sin was superbia, pride. But it was more complex than that; it included discontentment. A discontented spirit is both the fruit and the evidence of an ungodly heart."
