What does the Bible say about salvation being by grace?

Hebrews 2:17 emphasizes that Jesus is the merciful and faithful high priest who makes reconciliation for the sins of His people. This underscores a foundational truth of sovereign grace theology: salvation is entirely a work of God's grace through Jesus Christ, not based on human faithfulness or actions. Ephesians 2:8-9 further reinforces this, stating that salvation is a gift of God, not resulting from works, so no one may boast. This clarity on grace ensures believers understand that confidence in their faithfulness is insufficient; the only reliable ground for salvation is the faithfulness of Jesus Christ.
