When Jesus ministered to the sick, He said, “According to your faith be it unto you” (Matt. 9:29). Faith is simply believing what God says in His Word and acting like it’s true. Faith means acting on the Word!
Even if circumstances and situations around us tell us something different than what God says, we choose to still believe what God says about it. If our body and what we feel tell us something different than what God’s Word says, we still choose to believe what God says. If thoughts bombard our mind against what God says, we still choose to believe what He says.
