Ephesians 2:10 For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
Here we break from speaking of God’s revealed will to speaking of God’s secret will. This means not just the desires of God, but the plan of God that will come to pass by whatever means He chooses. When we refer to the revealed will, we mean that God has called us to do certain things and we should follow them. The secret will, however, describes the things that God has planned out before the creation of the world, the events and occurrences that He determines.
God generally carries out His will by means of people. While He has all the power to just make things happen on His own, He acts as more of a conductor who orchestrates the events rather than just making them happen by supernatural methods. We have choices in life and those choices lead to consequences. God sees to it that whatever the outcome, it coincides with someone else’s choice to bring about what He wills. Though He typically doesn’t force our hand, He does make things happen through our actions. And yes, at times He does intervene to provide the proper choices are made. This is hard to grasp, but consider the many accounts in the Bible where God stepped into a situation to bring about a particular result.
When we follow God’s (revealed) will, we work towards His (secret) will. Doing what He calls us to do leads to us playing a part in His plan, not only for our own lives, but in the overall plan He has.
