Preaching today is in rapid decline. Pulpits all over the planet are filled with ministers who gain a paycheck, but give little else. William Perkins explains what it means to be truly called to the holy office of the minister. He does this from two principle texts: Job chapters 32-33 with emphasis on 33:23, and Isaiah 6:1-13. Perkins says that the words in Job contain, “a valuable description of a true minister,” how he is a messenger and an interpreter, one in a thousand. Then, he explains Isaiah 6:1-13 of Isaiah’s confirmation, showing Isaiah was fearful, stunned, cast down, comforted, and renewed in his commission to go and be sent of God to preach for Christ's glory. He explains that men ought to consider the extreme presumption of those who rashly enter the ministry. Many ministers come into God’s presence unsanctified, and in their sins, little concerned about how loosely they live before their people. Perkins will not make the ministry an easy door to open. That is because faithful exegesis on important passages about the ministry shows it to be a hard and difficult road. Being God’s mouthpiece is not an easy task, but being called to it is an honor that is inexpressible.
