What scripture supports the need for Christians to set a good example?

1 Timothy 4:12 directly addresses Timothy to not let anyone despise his youth but to be an example to believers in various aspects of life. This serves as a directive for all Christians to actively cultivate an exemplary life. Additionally, Philippians 3:17 encourages believers to mark those who walk according to good examples, showing the communal responsibility to uplift and follow those who demonstrate a faithful walk with Christ. These scriptures both affirm the necessity of being an example and highlight the influence that individual believers have within the church.
