Very few of us like being told "no." But what happens when God says, "No." How do we react? How we react is a pretty clear picture of our spiritual maturity. In today's study in Acts, we see the Holy Spirit stopping the Pauline entourage from entering Asia and Bithynia. In the Christian vernacular, we often say that "God closed a door." To many, when that happens, it can be very devastating. Closed door are one of the most effective tools that the Holy Spirit uses to guide us.
