For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
1 John 5:4 (KJV)
The key to living a life of victory is our faith. Faith is a powerful spiritual principle that enables the promises of God to be made manifest in our life. We are called to strengthen our faith by exercising it like a muscle. The more that we exercise our faith, the stronger it becomes. We exercise our faith by setting our hearts and minds upon the promises of God, by meditating on them and confessing them until they become real to us. When we believe in the reality of something before we can perceive it through our physical senses, we are living in the victory of faith.
