Why is it important to defend the truth?

Defending the truth is a critical duty for believers as exemplified by Paul in Galatians 2:5, where he stresses the necessity of standing firm against error without compromise. The integrity of the gospel must be maintained in the face of false teachings. This call to defend the truth is not merely for the sake of doctrine but for protecting the spiritual wellbeing of the church community against influences that may dilute the true message of God's grace. A compromised gospel cannot save, making the defense of truth essential for faithful ministry.
