Those who love the doctrines of grace often forgot that it is not theologically incompatible to call sinners to faith and repentance as a dying man to dying men. We are, after all, "ambassadors for Christ, as though God were making an appeal through us; we beg you on behalf of Christ, be reconciled to God" (see 2 Cor 5:11-21).
In the history of the church no one exemplified this kind of evangelistic preaching better than Charles Haddon Spurgeon (note this). The following sermon from Dr. Lawson is a great example of how to preach the gospel (as a Reformed minister).
