As part of my own experience over the past 45 years, I've found myself struggling with the nature of faith having a primarily emotional element to it.
But getting back to Heb 11:1 - Faith must have "SUBSTANCE". Emotions don't and belief doesn't, and they're "Evidence" of NOTHING.
Mark 11:22-24 restates "Faith" as
"Believe in your HEART - NOTHING DOUBTING"
And, of course there's Rom 10:17 and Gal 3:2 (
The HEARING of FAITH).
Abraham "Believed God" - i.e. he believed in his HEART that if God said it to him, that settled it. God's WORD TO HIM had "Substance". Which is to say that BIBLICAL FAITH always has an element of REVELATION to it - i.e. GOD TOLD ME, and I can put my weight on that, and it'll hold me.
Emotions have nothing to do with it (although when significant stuff happens, there probably will be an "Emotional response").
God told me to pack up my life in Michigan, and move to North Texas in 1989. Since I was moving into a job where nobody I would be working with had any idea what they were doing, and they didn't have a product that made any sense, my "Emotions" could be expressed in negative numbers.
ALL I had to go on was God's WORD TO ME to join myself to a situation that made no technical sense at all. I put my weight on it, and it has held me for over 33 years, and led into some of the most valuable times in my life. Doing what I did was intellectually STUPID, but HE said to do it. So we did.
