Salvation through Christ is a gift of grace. Christ Himself is described as “full of grace” (John 1:14). A common definition of grace as used throughout the Bible is undeserved favor.
Dietrick Bonhoeffer (1906-1945) was a German pastor, theologian and anti-Nazi dissident. He was opposed to Hitler’s genocide of the Jews, and ran “underground seminaries” during the war. In 1943 he was imprisoned by the Gestapo. Bonhoeffer was executed in the spring of 1945.
