In her book, Hadfield explains that the "Name It and Claim It" principle is based on the idea that God's Word has creative power, and that believers can tap into this power by speaking their desires in faith. According to Hadfield, this approach to prayer and manifesting one's desires is grounded in Scripture, citing verses such as Mark 11:24, which states, "Therefore I tell you, whatever you ask for in prayer, believe that you have received it, and it will be yours."
