If evidence for god is in abundance, why is faith necessary?

 You need to supply those verses. By the way only God can save, but i doubt you understand this concept.

Keep your faith to yourself.

Matthew 6:1 "Beware of practicing your righteousness before men to be noticed by them; otherwise you have no reward with your Father who is in heaven.

Matthew 6:6 But when you pray, go into your room, close the door and pray to your Father, who is unseen. Then your Father, who sees what is done in secret, will reward you.
