Read Ephesians 1
Paul begins his letter to the church in Ephesus, a letter that was most likely meant to have a greater audience than just this one church, on a really high theological note. In fact, he basically sums up salvation history in this one chapter, and it all begins and ends with God.
There is a tenant in the Christian faith known as the doctrine of predestination that is something that has been talked about and debated over the years. Many different denominations of the Church see this differently. Essentially, the picture that Paul is trying to paint here is a God that is far above any confines of human existence. In fact, before the beginning began, God had worked out the plan of salvation and had even called people to Himself. This calling, which happened before all time began, is what we know of as Predestination.
Now, this particular doctrine also raises a number of questions for us. If God had the plan of salvation already worked out before He created the world, does that mean that God knew sin was going to happen? How could He allow that? Does that mean He created an imperfect world?
What about free will? Humans were created with the freedom to choose God or not, yet God already knows who He has called and who will respond? Doesn’t that conflict with free will?
These are good questions. The responses would take more time and are more nuanced than this writing has time for or can address. Some of it is beyond human understanding and comprehension. However, it may suffice to say that what we know as salvation history, as recorded in the Bible, is far greater, more thought-out, and abundantly more complex than we may have initially thought. Yet, even in that, God has taken care of every detail to the point that we cannot lose even a hair from our head without it being His will. Truly, He is amazing!
