God says to "meditate the Word by day and by night, and to incline your ear to His sayings" (Josh. 1:8; Prov. 4:20). The number one method God has chosen for us to use in increasing our faith is to exercise this spiritual law.
Faith comes by hearing, and hearing by the word of God.
(Rom. 10:17)
Beginning with the measure of faith residing within us, we apply this spiritual law by meditating the Word. God imparts the faith in that Word into our hearts, increasing our original measure. John 1:1 says, "In the beginning was the Word, and the Word was with God, and the Word was God." We can't reach out and touch God; but we can read His Word, which is the same as touching God. The Word is God.

God has faith because He is the Source of faith. When we go to the Word, God gives us faith to move the mountain of need. At times the mountain gets bigger as the need is greater. By meditating the Word, we get sufficient faith to take care of that need.

Let me warn you: Unless you have great faith operating in your heart, you will not get great faith results. Kenneth Copeland once said to me, "Start believing God now for your next pair of socks. Don't wait until you're faced with a life or death situation to develop your faith. The same principles that get you the socks will get you healed of sickness and disease."

Don't Get Weighed Down
If someone piled a small weight of things on your back, you would still be able to walk off easily. But as more things were piled on your back, you would have a harder time walking away. Eventually you wouldn't be able to move.

Many people are spiritually weak because they don't meditate the Word. The weight of needs piled on them cannot be dealt with by using the little faith they have. They should start developing their faith before needs begin weighing them down.
