How does God commend His ministers to the people?

God commends His ministers through the work of the Holy Spirit, which writes the gospel message on the hearts of the believers. As stated in 2 Corinthians 3:3, these believers become manifestly evident as the epistle of Christ, demonstrating that God’s grace has transformed their lives. The Spirit’s work in believers not only validates the minister's calling but also creates a powerful bond of trust between the minister and the congregation, as both parties recognize the divine origin of the message being preached. In this way, God establishes a clear testimony of the effectiveness of His ministers through the changed lives of His people.
