How do we know pastors should have a good testimony outside the church?

1 Timothy 3:7 states that a pastor must have a good reputation with those outside the church to avoid the risk of falling into reproach and the snare of the devil. This reflects the belief that a pastor's life should exemplify the transformative power of the Gospel, demonstrating authenticity and integrity. A good testimony acts as a witness to the grace of God in their life, showing the world that living for Christ changes lives. The pastor's life becomes a testimony that draws others to seek Christ.
