Faith says to God: “I believe what you say.” But reason scoffs.
When we pay attention to reason, God seems to propose impossible matters in the Christian Creed. To reason it seems absurd that Christ should offer His body and blood in the Lord’s Supper; that Baptism should be the washing of regeneration; that the dead shall rise; that Christ the Son of God was conceived in the womb of the Virgin Mary, etc.
Reason shouts that all this is preposterous. Are you surprised that reason thinks little of faith?
Reason thinks it ludicrous that faith should be the foremost service any person can render unto God.
Let your faith supplant reason!
From Martin Luther’s Commentary on Galatians
