faith

Faith is not belief in the unknowable.

Faith is the absence of doubt.

Doubt is that which saps the will.

Do you constantly spy on your spouse, expecting them to cheat on you?

That it doubt.

Do you trust them to do what is right?

That is faith.

Do you question things constantly, and believe that you can find a better way, a more just, more accurate, more complete way to accomplish things?

That is faith.

Do you lie in bed and say nothing has meaning, and nothing can be fixed, and life and the universe are random and unjust and unfair and nothing you do will ever matter?

That is doubt, which is the absence of faith.

Faith is belief, not in the unknowable, but belief that there is anything that can be known.

Faith is the knowledge that life can have meaning, that purpose can exist, that reason matters.
