Faith is knowledge of a higher sort.  We too often want to assess and evaluate faith compared to what we view as real, certain, and valuable (e.g. sensory experience) and as a result diminish faith.  However, if we understand faith from that which is highest and most conclusive, God’s revelation, it maintains for itself ultimate determining insight and power for the greatest benefit and outcomes.  Herman Bavinck has written in The Certainty of Faith

The Christian religion teaches us that the highest good for man is found in God alone, in fellowship with Him, in heavenly salvation.  Faith is a thoroughly personal matter, a retying of the bonds that tie the soul to God, a renunciation of all creaturely things to place all one’s trust in God, whether in life or death.  Faith is an inattention to the things one sees in order to take into account those that are invisible but yet eternal and imperishable.
