What does faith unfeigned mean in Christian teaching?

In 1 Timothy 1:5, faith unfeigned suggests a faith that is authentic and not superficial. This kind of faith is vital in a believer's life as it expresses true trust in God and manifests as charity in action. Such faith is characterized by consistency in belief and practice, motivated by love and a desire to serve God and others genuinely. The distinction is crucial because it indicates that mere intellectual assent is insufficient; a genuine relationship with Christ and His work in the heart must be evident.
