How do we know if a preacher is from God?

To determine if a preacher is truly sent from God, we can refer to 1 John 4:2, which states that every spirit that confesses that Jesus Christ has come in the flesh is of God. This confession is foundational, as it affirms both the divinity and the humanity of Christ, and how He became our substitute in bearing sin. Furthermore, true preachers will emphasize salvation through Christ alone, by grace alone, demonstrating a clear understanding of the gospel and the necessity of being born again. They will not rely on human works or the law, but will point to Christ as the source of righteousness and redemption, urging listeners to trust in His completed work on the cross.
