One thing I realized last year that makes surviving this time of year easier: it doesn't matter what the world is doing--Christ is coming anyway. Christ will come even if people go into mountains of debt. Christ will come even if our school teachers don't lead prayer in their classrooms. Christ will come even if we Christians miss it because we're too preoccupied what decorations are on the courthouse steps.
And for me, that means that Christ will come even if my sermon isn't life-changing. Christ will come if I don't have time to mop the kitchen floor. Christ will come, and I pray that I won't be too Christmas-ed out to miss it.
