Helmut Thielicke was a German theologian and professor that taught and wrote during WWII. He has some very helpful things to say about the liberating intention of the gospel and the connection between grasping mercy and knowing doubt. Here are a few of his insights.
“The Christian stands, not under the dictatorship of a legalistic ‘you ought,’ but in the magnetic field of Christian Freedom, under the empowering of the ‘You may.'”
“The gospel must be preached afresh and told in new ways to each generation, since every generation has its own unique questions. The gospel must constantly be forwarded to a new address, because the recipient is repeatedly changing his place of address.”
“Jesus did not identify the person with his sin, but rather saw in this sin something alien, something that really did not belong to him, something that merely chained and mastered him and from which he could free him and bring him back to his real self. Jesus was able to love men because he loved them right through the layer of mud.”
“I don’t believe that God is a fussy faultfinder in dealing with theological ideas. He who provides forgiveness for a sinful life will also surely be a generous judge of theological reflection. Even an orthodox theologian can be spiritually dead, while perhaps a heretic crawls on forbidden bypaths to the sources of life.”
“Tell me how much you know of the sufferings of your fellowmen and I will tell you how much you have loved them.”
“The doubters are always more blessed than the mere fellow travelers in faith. For they are the only ones who fully learn that their Lord is stronger than any doubt and any hell of despair.”
“What is the greatest deficiency among human Christians? They have an inadequate view of human suffering.”
