What is Faith?

What is faith?
is it something i don't have?
but how can i tell?

what is faith?
people say it is something you should have.
but when bad things happened i really don't have
any motivation.

they say faith means the courage to succeed in life.
but i really don't understand it.

i go to church to learn more about it but
i never seems to feel it.

so tell me what is faith?
is there a good kind and a bad kind?
will i ever make it to heaven without it?

they once told me that it is good and well help you
live freely. but i still worry, so all i wish is that i have that heart to except it in my life.
