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.
