Dietrich Bonhoeffer, born in 1906, was a brilliant German theologian and pastor who became a leading figure in the resistance against the Nazi regime. He was a co-founder of the Confessing Church, a movement that opposed the Nazification of the Protestant Church in Germany. 

Bonhoeffer is famous for his theological concept of "cheap grace" versus "costly grace," arguing that true faith requires a commitment to follow Christ's commands, not just intellectual assent. His best-known book, The Cost of Discipleship, explored this idea. 

During World War II, he became a double agent, working with the German military's counter-intelligence, the Abwehr, to secretly aid the resistance. He was involved in a plot to assassinate Adolf Hitler. His conspiracy was discovered, and he was arrested in 1943. After two years in prison, he was executed by the Nazis in April 1945, just a few weeks before the war ended.

"In me there is darkness,

But with You there is light; 

I am lonely, but You do not leave me; 

I am feeble in heart, but with You there is help; 

I am restless, but with You there is peace. 

In me there is bitterness, but with You there is patience; 

I do not understand Your ways, 

But You know the way for me." 

"Lord Jesus Christ, 

You were poor 

And in distress, a captive and forsaken as I am. 

You know all man's troubles; 

You abide with me 

When all men fail me; 

You remember and seek me; 

It is Your will that I should know You 

And turn to You. 

Lord, I hear Your call and follow; 

Help me."
