In this passage, we learn the duties of a Christian Preacher. This is not just applicable to seminary students, pastors and scholars, but this is applicable to lay Christians as well. It’s applicable to Christians, because they’re called to protect themselves and others in the church from false teaching or even teachings that may not be related to the message of salvation. Christians are called to evaluate a Preacher’s preaching, because it’s only through proclaiming Jesus Christ and Him crucified can a person be saved, and this is the only way can a Christian grow spiritually. Gospel must be at the center of every faithful preaching.
