How would you define faith?
Latter-day Saints often use Hebrews 11:1 “Now faith is the substance of things hoped for, the evidence of things not seen.” They believe that faith is the first principle of the gospel.
I believe faith is the basis of Christianity. Christians believe we are saved by grace through faith. We are justified by faith.
Unfortunately, many people in the world have a wrong impression of faith. They think faith is something that is blind. They think those who have faith are those who believe in something that has no evidence.
