Why is justification by Christ alone important for Christians?

The importance of justification by Christ alone lies at the heart of the Gospel, which teaches that our standing before God does not depend on our actions or faithfulness, but wholly on Christ’s completed work. This doctrine provides profound comfort and assurance to believers, knowing that their sins are completely dealt with and God's justice has been satisfied through Christ’s sacrifice (Romans 5:9). It also emphasizes grace, showcasing that salvation is unmerited and freely given to the elect, fostering a humble reliance on the grace of God rather than on personal merit (Ephesians 2:8-9). By understanding justification in Christ alone, believers gain a deeper appreciation for God's mercy and a rightful response of gratitude and obedience in their lives.
