Ezra - Chapter 8
Ezra is on a long and potentially dangerous journey. He refuses to ask for human help, because he does not want to show a lack of faith in God. Instead he prays to God for protection, and God answers this prayer:
"There, by the Ahava Canal, I proclaimed a fast, so that we might humble ourselves before our God and ask him for a safe journey for us and our children, with all our possessions. I was ashamed to ask the king for soldiers and horsemen to protect us from enemies on the road, because we had told the king, “The gracious hand of our God is on everyone who looks to him, but his great anger is against all who forsake him.” So we fasted and petitioned our God about this, and he answered our prayer."
In Matthew 21 Jesus tells his disciples that this is the way they should approach prayer:
"Jesus replied, “Truly I tell you, if you have faith and do not doubt, not only can you do what was done to the fig tree, but also you can say to this mountain, ‘Go, throw yourself into the sea,’ and it will be done. If you believe, you will receive whatever you ask for in prayer.”"
