Why should Christians avoid boasting in their righteousness?

The danger of boasting in righteousness is addressed in Deuteronomy 9, where Moses reminds the Israelites that their entrance into the promised land is not earned by their own merit but rather through God's grace. This principle is essential for understanding the gospel; if salvation were based on human righteousness, it would negate the work of Christ, who alone fulfills the law perfectly. Scriptures such as Ephesians 2:8-9 reinforce this, emphasizing that we are saved by grace through faith and not by works, allowing none to boast. This humbling truth positions us as recipients of God's mercy rather than as self-sufficient beings.
