So Joseph went from the Galilean town of Nazareth up to Bethlehem in Juday, David's town, for the census. As a descendent of David, he had to go there." Luke 2:4
Sometimes when God is planning a big arrival in our lives; when He is going to move big in our lives to affect others or our own lives or show Himself to us in a new way, He has to move us. Maybe He actually causes us to move to a different location permanently. Or, He sends us somewhere at the most inconvenient time (remember, Mary is like 9 months pregnant -- not a good time for her to travel). Or, He rearranges people or events in our lives to make room for His arrival -- His new way of showing Himself to us.
These changes of circumstance might cause us to be anxious or fearful or irritated or even angry. But let's let God be God. Let's let Him do what He needs to do to "arrive" in the midst of our lives. When we naturally react to these inconvenient things that disrupt our schedules, our routines, let's pray for God to open our hearts, ears and minds and eyes to see where He intends to show up.
Often, the interruptions in our lives (or the events you go to because you feel you ought to be there but you'd rather stay home and watch TV) are orchestrated by God to be used by Him in a totally unexpected, unimagined way.
Let's let God be God in our lives.
