The Rev. Dr. Ken Korby left a great impression on many pastors and laypeople. One impression he left on me was the distinction between preaching Christ and preaching about Christ. He illustrated it in this way:
If you were standing before a judge, having been condemned and convicted of a crime, could you tell the difference between the judge talking about a parole and the judge actually declaring that you are paroled?
The Gospel is not telling people about Jesus. It is, as the apostle Paul declared, preaching Christ -- and Him crucified (1 Cor. 1:23; 2 Cor. 4:5; Phil. 1:15-16; Col. 1:28).
Lutheran pastors don't merely preach about forgiveness, they forgive in the name of the Father and of the Son and of the Holy Ghost.
