Thoughts: Perhaps this is the first hint at an eclipse in the Bible. It is in the context of what happens when we do not obey the Lord.
It is a reminder that it is not good to be blind at midday. We take for granted we can see in day or night because we can just turn on the light. But in the ancient world (and still in the world with little electricity or ability to buy batteries) in the dark you were indeed blind and groping about like someone mad or confused. The point here is that if we disobey God we will be blind to our hope and cannot see our purpose and direction. We will be like a person who is lost. An eclipse at midday is a reminder of spiritual eclipse. We should not let anything get in the way or block our view of God's light in our lives.
Prayer: Lord, there are many who would stand in the place that would keep me from seeing your light. Help me to follow your light. Your Word is a lamp unto my feet and a light unto my path (Ps. 119:107).
