Sight is not faith, and hearing is not faith, neither is feeling faith; but believing when we neither see, hear, nor feel is faith; and everywhere the Bible tells us our salvation is to be by faith. Therefore we must believe before we feel, and often against our feelings, if we would honor faith.
This is a beautiful time, this last age, the age of the Holy Spirit. . . He is crying to every soul that is walled: Open to Me, My spouse, My sister. And once inside, He is calling again: Come to Me here in this secret place. Oh, hear Him tonight crying all over the world a last desperate summons of love to a dying race.
Above all, you ask if the God of Christians forgives those who do not believe and who do not seek faith. Given the premise, and this is fundamental, that the mercy of God is limitless for those who turn to him with a sincere and contrite heart, the issue for the unbeliever lies in obeying his or her conscience.
