How long wil you waver between two options?

1 King 18:16-40
Ahab thought Elijah is trouble of Israel. Actually, Ahab and his family have troubled Israel. He has abandoned the Lord's commands and have followed the Baal's.
"How long will you waver between two options, is the Lord or Ball?", Elijah asked Israel, but they said noting.
Elijah said to them, prepare two bull and let them cut it into pieces and put it on the wood, but not set fire on it. Then call on the name of your God. I will call on the name of the Lord, The God who answered by fire - he is God.
The prophets of Ball and Asherah, 850, shouted louder and slashed themselves with swords and spears from morning until the time for the evening sacrifice. But there was no response, no one paid attention.  It could seen in ceremony of many paganism.
Elijah called to the Lord 'Answer me, O Lord, answer me so that those people will know that you are God and turning their heart back again'. The fire of the Lord fell and burned up the sacrifice the wood, the stones and the soil and also water licked up in the trench.
All the people saw this they fell prostrate and cried "The Lord - he is God, The Lord he is God.'
Elijah commands them, seize the prophets of Baal. Don't let anyone get away! They seized them, and Elijah had them brought own to the Kishon Valley and slaughter there.
Why?
The Miracle shows the power and glory of the Lord. Let people knows He is God and turn their heart to the Lord.
The Lord is the fire who burn all the evil things.
How?
Christian as me usually will waver our mind between two options. Not the Lord and other God, but hesitate between solve problem by the way of world or the Lord's way, buy this one or that one, forsake this or forsake that one.
May the Lord reminded me when I make decision with the wisdom of Spirit and honor name of the Lord.
