As we journey through life toward Heaven, He dispenses faith in proportion to that which we face. You see, faith is like a muscle. When it’s taken into the gym of life, it can do little in the beginning, but, as it’s exercised in the little things, day by day it grows considerably until it’s able to accomplish great things through Jesus. Now, how does one go about exercising faith?
Rom. 10:17. So then faith cometh by hearing, and hearing by the word of God.
As we hear the Word of God and take God at His word by faith, our faith grows stronger and stronger. But, in reality, it isn’t our faith that grows stronger, it's His faith within us that increases as we grow.
