Preaching as Worship - Preaching (or, as he said, any Bible handling in whatever situation - think evangelistic Bible study, small group talk, CU meeting,...) is, in the words of Cotton Mather, "restoring the throne and dominion of God in the hearts of men."
Preaching that Speaks to Suffering and Evil - let "our preaching combine heart-wrenching weeping with unbreakable confidence in the sovereignty of God" (Piper)
Preaching the Cross -
"Lots of people would like you to not preach the cross. Non-Christians find it offensive. Some Christians think it is dull, or the basics that they have gone on from and grown out of. Some think that its just an old message with little contemporary excitement because they’ve heard it all before.
But I tell you that there is no glory in Christianity without the cross. There is no glorious message for us to proclaim without the cross. There is no power to save those who believe, no grace, no work of the Holy Spirit. Galatians 3 says that you grow as a Christian having the Holy Spirit and knowing him working miracles among you because you believe the message of Christ crucified. And without the message of the cross the gentiles are nor brought as a fragrant offering to God for his praise."
