How many people pray daily?

Only God can answer that question. But why should we pray? Because it is the one and only way to communicate our appreciation for what he gives us on daily bases and also ask him to help us according to our needs. Read James 1: 5.

Strength and confort come from our heeavenly Father. Read Philippians 4: 13 which reads. "For all things I have strength through the one who gives me power."
