What does the Bible say about the purity of grace?

The Bible teaches that the purity of grace is essential as it underscores the core of the gospel—salvation is entirely a work of God and not reliant on human efforts. In Ezra 4, the adversaries of Judah and Benjamin attempted to join the Israelites in rebuilding the temple, claiming to worship the same God. However, their understanding and practice of worship were corrupted, showing that true worship must align with the character of God as revealed in Scripture. This purity of grace rejects any mixture of works and grace, reinforcing that God’s grace is the only means by which we are saved and justified before Him.
