What kind of courage? Courage is required when you are in a situation that you fear something. Elijah testified that is was the Lord God of Israel that he stood before. It seems to be more about obedience than courage. I realize he was entering into a confrontation with spiritual and national leaders, but he knew who it was that he was really standing before was God Almighty. When your eyes are fixed on God, the fear of man has no power over you. Easier said than done many times, but I think Elijah at this moment had that figured out before he went in to the room before Ahab.
Elijah knew it was only at his word that rain and dew would come to the land once again. Therefore, he knew he would be around for a few more years to release that word. He could be confident as he entered and just as confident when he turned and left.
“Speaking truth to power” would be difficult when you are more afraid of the person you are confronting than the God who is sending you. We need more of the fear of the Lord on God’s people today.
