Word of Faith

Word of Faith (also known as Word-Faith or simply Faith) is a worldwide Christian movement; it teaches that Christians can access the power of faith or fear through speech. Its distinctive teachings are found on the radio, Internet, television, and in many Christian churches. The basic doctrine preached is that of wealth and health through the declaration of what the Bible (The word of God) said with regards to living wealthy and healthy.

The Word of Faith movement has many distinctive teachings including physical, emotional, financial, relational, and spiritual healing or prosperity for any who has the right belief-filled confession. The movement emphasizes choosing to speak the promises and provisions that the speaker wants, that is in agreement with the Bible, as an act of faith and agreement with God's plans and purposes. They believe this is what Jesus meant in , when he said believers shall have whatsoever they say and pray with faith. The term word of faith itself is derived from the biblical passage which speaks of the word of faith that we preach.
