God’s Synergy is Romans 8:28—He causes all things to work together for good to those that love Him, to those who are called according to His purposes. Here is a sermon by Jerry Newcombe (the message starts about 3 minutes in and lasts about 30 minutes) on the subject of Romans 8:28-39. This is one of the most beautiful passages in the Word of God.
This was delivered on Sunday night, May 14, 2017. (Video, courtesy of Tim Savage).
