The Lord is Peace, Gideon built a altar

Judges 6:1-24
"Pardon me, my lord,” Gideon replied, “but if the Lord is with us, why has all this happened to us? Where are all his wonders that our ancestors told us about when they said."
Ans. I am theLord your God; do not worship the gods of the Amorites, in whose land you live. But you have not listened to me.
Go in the strength you have and saveIsrael out of Midian’s hand. Am I not sending you? Angel told Gideon 
But how can I save Israel? My clan is the weakest in Manasseh, and I am the least in my family.
If now I have found favor in your eyes, give me a sign that it is really you talking to me. 
Gideon built an altar to the Lord there and called it The Lord Is Peace. To this day it stands in Ophrah of the Abiezrites.
Why?
Many people will ask the same question like Gideon, Why has all this happened to us? The answer is simple, because they do not listen to the word of God.
Gideon did not know who the angle was, so he asked the angle give him a sign.
Gideon is humble and careful to listen angle's talk.
Finally Gideon built a altar to the Lord, remember that the Lord is Peace.
If we do not sure the way God assigned to us, we can ask the Lord give us a sign.
How?
The Lord is peace, but there are many war and disaster in the world because they did not listen to the word of God.
