How do we know grace is sufficient for justification?

Grace is the cornerstone of biblical justification. Ephesians 2:8-9 underscores that we are saved by grace through faith, and this is not of ourselves; it is a gift of God. This foundational truth teaches us that justification is entirely a work of God, not dependent on human effort. The reality of redemption and justification through grace is established throughout the Bible, particularly in Romans, which emphasizes that the righteousness of God is revealed apart from the law and is accessible to all who believe.

When we look at the life and work of Jesus Christ, we see that He fulfilled the law perfectly and then offered Himself as a sacrifice for our sins. God’s grace provides the means for our justification, standing as an unmerited favor toward sinners. This grace assures us that despite our sinfulness, we can be declared righteous in God's sight through faith in Christ’s finished work. Thus, we are reminded that grace is indeed sufficient and entirely sufficient for justification.
