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

[ComradeMeow]

When I was a Muslim there never was this strong concept of faith, I was merely taught that a god is self evident and as real as the stars and earth. I would not say all religions teach faith like Christians profess. This would be an oversimplification of what is at hand when it comes to the religious theists. Instead I would ask why is there so much certainty in god or can you imagine a world without it. Even when my own mother brought this up she said she would flat out murder people if there was no god yet in reality she is a very dishonest and manipulative person who uses a god to confirm her own immorality and not the reverse. So things like this bug me but not as much as whether faith is necessary for theists.

Everybody exhibits faith in their life, as we all do that the earth won't get hit with a meteor the next day. If we did not we would all be owning bunkers at the moment and only invest in subterranean real estate. Faith is not as real to Christians or Muslim as it is certainty in god's existence and presence in their life.

Muslims just like Christians take a god and reflec all their behaviour back to that imaginary being despite their own capabilities. I know Muslims who excel in mathematics and profound concepts but reflect this all to a deity but never to themselves. It makes you wonder why they studied so hard and worked for what they wanted to begin with if their "lives are in God's hands."
