Why is it important to have faith that is genuine and unfeigned?

The concept of unfeigned faith, or genuine faith, is central in Paul’s encouragement to Timothy in 2 Timothy 1:5. Such faith is not an act; it is a sincere trust in God that stems from a deep relationship with Him. It acknowledges Christ's work in salvation and signifies a genuine commitment to live according to His will. This kind of faith enables believers to endure challenges and afflictions as it rests firmly on the truth of the Gospel, ensuring they do not waver in their convictions even in difficult times.
