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.
Christianity doesn’t demand us to perform many rituals and sacrifice to Idols or become a monk, but it demands us to forsake our selfishness and pride; only then are we able to believe that Christ is the only Savior of our lives because we couldn’t save ourselves from God’s righteous judgment. In this passage we learn how God chooses unintelligent people, people with low social status, people who are not very influential, demonstrating His grace to those who are helpless and crushing the pride of those who believe they are self-sufficient, wise and powerful enough.
