I wonder how it would have went if they did not really believe. According to your faith... God tells us that faith as a grain of mustard seed will result in our being able to tell a mountain to be cast into the sea and it will be done. He says in James that if lack wisdom, as these lacked sight, that we should ask of God, and God will give us our request NOTHING DOUBTING. According to your faith. Jesus went to his home town and could do very little there because of their lack of faith.
One day we will be judged, the sheep shall seperated from the goats, the wheat from the chaff, the goats shall depart into everlasting hellfire, the sheep to eternal life. You will be one or the other according to your faith.
