The Art of Divine Contentment: An Exposition of Philippians 4:11 by Thomas Watson. Excerpt 43

Watson continues discussing reasons to be contented, or "contentation," as he puts it.

Sect III. The third argument is,
Be content, for else we confute our own prayers. We pray, “thy will be done:” it is the will of God that we should be in such a condition; he hath decreed it, and he sees it best for us; why then do we murmur, and are discontent at that which we pray for? either we are not in good earnest in our prayer, which argues hypocrisy; or we contradict ourselves which argues folly.

Sect IV. The fourth argument to contentment is,
Because now God hath his end, and Satan misseth of his end.
1. God hath his end. God’s end in all his providences is to bring the heart to submit and be content; and indeed this pleaseth God much, he loves to see his children satisfied with that portion he doth carve and allot them; it contents him to see us contented; therefore let us acquiesce in God’s providence, now God hath his end.
2. Satan misseth of his end. The end why the devil, though by God’s permission, did smite Job in his body and estate, was to perplex his mind; he did vex his body on purpose that he might disquiet his spirit. He hoped to bring Job into a fit of discontent; and then that he would in a passion break forth against God: but Job being so well-contented with his condition as that he falls to blessing of God, he did disappoint Satan of his hope. “The devil will cast some of you into prison; (Re. 2. 10) why doth the devil throw us into prison? It is not so much the hurting our body, as the molesting our mind, that he aims at; he would imprison our contentment, and disturb the regular motion of our souls, this is his design. It is not so much the putting us into a prison, as the putting us into a passion, that he attempts; but by holy contentation, Satan loseth his prey, he misseth of his end. The devil hath often deceived us; the best way to deceive him, is by contentation in the midst of temptation; our contentment will discontent Satan. O, let us not gratify our enemy! discontent is the devil’s delight; now it is as he would have it, he loves to warm himself at the fire of our passions. Repentance is the joy of the angels, and discontent is the joy of the devils; as the devil danceth at discord, so he sings at discontent. The fire of our passions makes the devil a bonfire; it is a kind of heaven to him to see us torturing ourselves with our own troubles; but by holy contentment, we frustrate him of his purpose, and do as it were put him out of countenance.

Thomas Watson lived from 1620-1686, in England. He wrote several books which survive. This blog, God willing, will post excerpts from his The Art of Divine Contentment: An Exposition of Philippians 4:11, over a number of weeks, on Sundays.
