How do we know if we have saving faith?

In John 8:31, Jesus tells those who believe in Him that if they continue in His word, they are truly His disciples. This enduring faith is not merely a one-time event but a continuous reliance on Christ. The Scriptures affirm that faith itself is a gift from God, bestowed by His power (Ephesians 2:8-9), and is evidenced by the fruits of obedience and perseverance. True saving faith is characterized by a life that clings to Christ, despite struggles and doubts, and thus reflects the work of God within us.
