Why is it important for Christians to understand that Christ is enough?

Understanding that Christ is enough is foundational for a believer's faith. It releases them from the burdens of trying to earn God's favor through works, emphasizing that salvation is by grace alone through faith, as stated in Ephesians 2:8-9. This truth allows Christians to rest in the completed work of Christ, knowing that they do not need to add anything to their salvation. It affirms the comprehensive nature of God's provision for His people, who receive all that is necessary for salvation and sanctification in Christ alone.
