Stop praying for big muscles and start now to do as many push-ups as you can. If you really want bigger, stronger muscles, do the push-ups day by day. Each week add two or three more. In short order you will see God's answer to your prayer.
“Oh” you say, "but that would be ME doing it."
Really? Who put those little muscles inside your body?
Stop praying for faith and use the measure you have.
