Why is it necessary for Christians to have faith in Christ?

Faith is not merely intellectual assent; it is trusting in Christ alone for righteousness and salvation. Ephesians 2:8-9 reminds us that we are saved by grace through faith, emphasizing that our own works are insufficient to earn God's favor. This faith transforms our hearts, enabling us to escape the prison of our sins and to embrace the freedom found in Christ. Understanding our position, that we can do nothing to save ourselves, drives us to place all our hope in Him, acknowledging that He alone is our hiding place from judgment.
