If Elijah were alive today, would he not say the same things to us? Would he not tell us to quit wavering? He would say to either sell out to God or to sell out to a false god. If your false god (little g) is your god, then sell out to it. If money is your false god, get into massive debt, steal if you have to and don't ever give again because that would diminish your own
BUT....if God is your one true God, then serve Him with all of your heart. Can you feel the power of Elijah's words? It was a true show down. He tells the people to decide firmly who they will serve. For those wavering, he challenges them to watch the power of their gods.
