God's Word will begin to govern our outlook and behavior. Faith therefore, affects the whole life of a believer. The exercise of faith in a believer's experience brings about a total change of life that accords with the Word of God.
Jesus said, "If you continue in my Word, then you are my disciples indeed, and you shall know the truth, and the truth shall make you free." (John 8:31-32)
The source of faith is Jesus Christ, and He shapes the faith that we have. God deals with each one of us on a personal basis. He purposefully makes a measure of faith for each person, and from there onward the individual grows in faith as he responds to each opportunity that he or she has to act in faith!
The first challenge to operate in faith in a believer's life will lead to the next experience and challenge, and so on. The Bible describes this as going "from faith to faith" (Romans 1:17). This could be compared to a man who owns a well. Each bucket of water he brings to the surface adds more water to the reservoir at the top.
Faith comes by hearing the Word of God (Romans 10:17). The Bible is the supply line of faith. By this we understand the importance of knowing the Scriptures.
