This verse tells us that “all things work together for the good of those who love God.” If we love God, then we live in obedience. The “all things” refers to the providence of God and all the things that relate to Him: His Holy Spirit, His love and mercy, His truths, etc. All of these things come together for our good if we love God and show that we do by our behavior. But it’s not only required that we love God, but that we are called according to His purpose. This refers to the purpose that God has set before us. He calls us to a specific purpose in this life. As long as we are obedient to this purpose, to His call, then all of His resources come together for our good. This is a very encouraging scripture to let us know that, if we follow the will of God, everything will be okay with us. More than okay, actually. They will be “good,” because God is on our side.
