It is an emotional appeal.
That doesn't make it bad - it just is what it is.
It's not "proof" of anything, but that's what faith is. My only objection comes when that faith gets confused with something else, like scientific evidence.
I'm glad that you feel so strongly that your faith is correct. But everyone has those feelings about their faiths. Those feelings don't make their faith the One True Faith and yours wrong, or vice versa.
You have been polite and friendly. I appreciate that.
Nonetheless, I will point out that this is objective.
It asks you to follow the path, and then you will know.
