Everything produces after its own kind. That is the law of Genesis. Everything you have right now was given to you when you were born. You didn t have to go out and get hands later on. That would be as silly as you praying for hands.
People produce people.
When you turned one year old, they didn t cut off your newborn hands and put one year old hands on you, and when you turned five, they didn t cut off your year old feet and put on five year old feet. Within your body when you were born was the capability to increase to the size it is today. That potential was there when you were born. You do not need to pray for more faith. The faith you were given when you were born again has within itself the capability of increasing.
