Hebrews 11:6

Without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.

Faith is the powerhouse to our lives.  The amount of confidence we apply to our relationship with God and His Word will determine whether we overcome and fulfill the plan God has for our lives. We build up our faith by repetition like a bodybuilder uses weights.  The more we increase our use and study of the Bible, the stronger we will become on the inside, and our Faith will build muscle.
