Faith is what Hebrews was all about. Faith is what causes us to walk where there is no ground and fly when there are no wings. Faith acts according to what God has promised, not according to the visible evidence. Eyes see walls and obstacles and giants and the body in response runs away. Faith sees victory in spite of the obstacles because God has promised it and the body moves forward.
Faith works. Where the body does not move forward in action there is no faith. Faith works.
The statement faith and works is misleading as it implies you can have one without the other. James says simply faith without action (works) is dead.
Sunshine. Sun = faith, shine = action
You can't have a sun without shine...
If you truly believe your actions will show it. If they do not it is not because you lack shine; it is because you lack the Son.
