How do we know the authority of the church's witness is true?

The authority of the church's witness is affirmed through God's promise to empower it as His witness on earth. It is not by human might or power, but by His Spirit that the church bears witness. This divine authority enables the church to declare the gospel effectively, emphasizing the necessity of faith in Christ for salvation. As revealed in Scripture, God supports the church’s calling to testify about Him, and its words are compared to fire—capable of piercing hearts and convicting minds (Jeremiah 5:14). This is a testament to the ongoing relevance and truth of the church's witness throughout the ages.
