Faith is not belief without proof, but trust without reservation.

From Hebrews 11:1-3:  “Now faith is the assurance of things hoped for, the conviction of things not seen.  Indeed, by faith our ancestors received approval.  By faith we understand that the worlds were prepared by the word of God, so that what is seen was made from things that are not visible.”

Elton Trueblood (1900-1994) was an American Christian author and theologian.  He served as chaplain to both Harvard and Stanford universities.
