Faith is built on hope. Faith has power and causes things to change: "By faith people passed through the Red Sea as on dry land... By faith the walls of Jericho fell...By faith the prostitute Rahab, because she welcomed the spies was not killed..." (Hebrews 11:29-31 NIV edited). And the amazing thing is, this power is in our hands. We can choose whether of not to live in the faith zone.
