The eye of faith!

(Alexander Smellie, "The Hour of Silence" 1899)

"Now faith is the assurance of things hoped for, the conviction of things not seen." Hebrews 11:1

Faith beholds invisible realities! It is the conviction of things not seen. It brings the great realities of the spiritual world within my reach:
  God, in His glory;
  Christ, in His beauty and love;
  sin, in its deformity;
  holiness, in its excellence;
  the solemn judgment to come;
  eternity, so blessed — or so sad.

Faith gives me a firm persuasion of these unseen realities. It invests them with a transforming influence over my heart. I look out, with the eye of faith, and I find myself in their midst.
