A key point about faith is understanding that you cannot live successfully by your power but by the grace of God.
God, realizing that you trust Him for help, supplies you with all you need as long as you have faith (trust) in Him from start to finish.
Christian’s relationship with God is all about exercising faith in Him.
Romans 1:17 NIV
[17] For in the gospel the righteousness of God is revealed—a righteousness that is by faith from first to last, just as it is written: “The righteous will live by faith.”

If Christians do not apply faith appropriately, they cannot live a successful life.
