I do not care how I feel, and neither should anyone else.
I feel all kinds of stupid things all the time, and I cannot afford to take them seriously.
What matters — what I take seriously about myself — is what I decide, what I will, what I do.
And what I will is a product of how I think.
How I think is who I am.
How a person thinks is connected with but not the same as what a person thinks.
To know a person’s beliefs is not to know that person’s faith.
We conflate belief and faith because we have never learned how to understand faith. One must have a certain faith to know faith and I suppose that is probably what Christians call “grace”.
