Why is discerning the truth important for Christians?

Christians are called to discern truth from error, especially in a world saturated with diverse opinions and teachings. The apostle John emphasizes this necessity in 3 John by contrasting a faithful brother, Demetrius, with Diotrephes, who acts against the truth. Discerning the truth requires knowledge of Scripture and the work of the Holy Spirit, which enables believers to recognize and reject teachings that do not align with Christ's revelation. Furthermore, this discernment fosters unity and love within the church, as holding to the true gospel allows for genuine affection among believers. Without such discernment, the church risks being led astray by false gospels that deviate from the essential truths of Christ’s atoning work.
