Now faith is confidence in what we hope for and assurance about what we do not see. Hebrews 11:1
Now faith is the substance: Just as our physical eyesight is the sense that gives us evidence of the material world, faith is the “sense” that gives us evidence of the invisible, spiritual world.
Faith has its reasons. We aren’t talking about a “blind leap” of faith. But the reasons can’t be measured in a laboratory, they have to be understood spiritually. David Guziks Commentary
