Pastor Jim Cymbala challenges pastors to simplify their message. The good news of salvation through Jesus Christ is all we need. We don't need to add stuff to it. We don't need to get diverted into extra-biblical topics or legalism. If it isn't in the New Testament, don't preach it. Don't mix the old covenant in with the new and better covenant. Sometimes the hardest part of rightly dividing the word of God is the Old and New Testament.
