"For We Walk By Faith, Not By Sight" - (2 Corinthians 5:7)
Faith is taking God at His word. Faith is not belief without evidence. It is belief on the very best of evidence - the Word of Him "that cannot lie" (Titus 1:2). Faith is so rational that is asks no other evidence than this all-sufficient evidence. To ask other than the Word of Him who cannot lie is not rationalism, but consummate irrationalism - Dr. R.A. Torrey
When we can see, it is not faith but reasoning. Look at the faith of the master mariner! He looses his cable, he steams away from the land. For days, weeks, or even months, he sees neither sail nor shore; yet on he goes day and night without fear, till one morning he finds himself exactly opposite the desired haven toward which he had been steering. How has he found his way over the trackless deep? He has trusted in his compass, his nautical almanac, his glass, and the heavenly bodies; and obeying their guidance, without sighting land, he has steered so accurately that he has not changed a point to enter port.
It is a wonderful thing - that sailing or steaming without sight. Spiritually it is a blessed thing to leave altogether the shores of sight and feeling; to say "Good-bye" to inward feelings, cheering providences, signs, tokens, and so forth. It is glorious to be far out on the ocean of Divine love, believing in God, and steering for Heaven straight away, by the direction of the Word of God (and the instruction of the Holy Spirit - cj's note).
