How do we know true faith is important for Christians?

True faith is emphasized throughout scripture as a non-negotiable aspect of the Christian life. In Jude, believers are encouraged to contend for the faith that was once delivered to the saints. This contention is rooted in the understanding that true faith is evidenced by a life transformed by the gospel. It is not merely an intellectual assent to doctrine but an active, living faith that manifests in the way we treat others and pursue holiness. The failure to uphold this faith can lead to destructive behaviors and a lack of reverence for God's authority. Thus, it is essential for Christians to ensure that their faith is genuine, which will naturally lead to a life that glorifies God.
