How do we know if a preacher is telling the truth?

Determining the truthfulness of a preacher involves a careful evaluation of their message based on the infallible Word of God. John emphasizes in 1 John 4:1 that believers should not simply accept every claim made by preachers but should test these claims. A faithful preacher will consistently align their message with Scripture, declaring the Gospel of grace. Moreover, the Spirit of God will affirm the truth in a believer’s heart when they hear the true Gospel. This discerning process is essential for maintaining doctrinal purity and protecting against falsehood.
