Even unbelievers have been given the measure of faith. That kind of faith is counted unto us for righteousness by G-d. That is the kind of faith that causes us to never cave in, never give up, never fail. That kind of faith causes us to press on all the way through to victory until we go to heaven to live with Yeshua. Faith functions according to how much fear which we allow to come into our life.
Fear is the devil's kind of faith.
The devil has an antidote for every good thing that G-d wants to give us. G-d wants us to be generous and giving and Satan wants us to covet and be stingy. Fear is the satanic counterpart that comes against faith. Sometimes it is very helpful to think about our thinking and see if some of our thinking is stinking thinking. It is a choice.
