In the Old Testament reading, God tells Elijah to come outside and watch him pass by.
Usually, the Old Testament reading gives us the context for the Gospel. But sometimes the Old Testament reading could use a little context itself - here's the context for God's "invitation" to Elijah.
Earlier in the Old Testament, when Jacob finds out that he is wrestling an angel, he is amazed that he has seen an intermediary of God and is still alive. And when Moses asks to see God, God warns Moses that no one can see God's face and live. Elijah knows all of this, which is why he isn't doing the asking.
So for God to invite Elijah to come outside and watch him pass by is, well, scary, or a sign of God's favor, or some of both. Either way, it's kind of a big deal.
