Jesus gave us what the spirit of prayer is: "Men ought always to pray and not to faint". That carries the spirit of prayer, from the Old Testament to the New. This is what these episodes expose to us. God has principles. The Old Testament patriarchs and prophets practiced it. Jesus exemplified and taught it. Prayer is a serious business that stretches long, but produces the result speedily in the day of the answer. This is interesting. You'll surely be baptized fresh. Tell others.
