What is the difference between faith and assurance in Christianity?

The distinction between faith and assurance is often misunderstood. Faith is the trust and belief in God and His promises, primarily in the person and work of Christ. Assurance, on the other hand, is the certainty that comes from that faith, providing believers with confidence in their salvation. According to 1 John 5:13, assurance stems from believing in the name of the Son of God and understanding His sufficiency to save. True assurance cannot be found in our works or in our emotional states, but must rest solely in the steadfast character of Christ and His unchanging promises.
