Because peace is a fruit of the Spirit, we are dependent upon the Spirit's work in our lives to produce the desire and the means to pursue peace. But we are also responsible to use the means He has given us and to take all practical steps to attain both peace within and peace with others.
Jerry Bridges... self-control is not control by oneself through one's own willpower but rather control of oneself through the power of the Holy Spirit.
Jerry BridgesTo derive the fullest comfort and encouragement from Romans 8:28 we must realize that God is at work in a proactive, not reactive, fashion. That is, God does not just respond to an adversity in our lives to make the best of a bad situation. He knows before He initiates or permits the adversity exactly how He will use it for our good.
