My wife makes an amazing pot roast dinner. She takes raw meat, along with raw sliced white and sweet potatoes, celery, mushrooms, carrots, and onions and throws them into the slow cooker. Six or seven hours later the aroma fills the house, and the first taste is a delight. It is always to my advantage to wait until the ingredients in the slow cooker work together to achieve something they could not achieve individually.
When Paul used the phrase “work together” in the context of suffering, he used the word from which we get our word synergy. He wrote, “We know that in all things God works for the good of those who love him, who have been called according to his purpose” (Rom. 8:28). He wanted the Romans to know that God, who didn’t cause their suffering, would cause all their circumstances to cooperate with His divine plan—for their ultimate good. The good to which Paul referred was not the temporal blessings of health, wealth, admiration, or success, but being “conformed to the image of [God’s] Son” (v. 29). [Marvin Williams, odb.org]
