Wisdom from Martin Luther:
We must learn to know the power and might of God in this same Word, namely, that we are saved thereby and solely by it resist the devil’s power and all errors. For to believe firmly that I am a Christian, a child of God, and that I am saved, when I feel sin and a bad conscience; to believe that I will live eternally, endowed with a beautiful, glorious body, although I lie under the sod—that requires a divine and heavenly power and a wisdom which is not governed by any feeling or perceiving, but which can look beyond that, convinced that this is not human prattle or phantasy but that it is the Word of God, “who is able to do far more abundantly than all that we ask or think” (Eph. 3:20).
