What does the Bible say about salvation by God's grace?

The Bible clearly affirms that salvation is of the Lord, as seen in 2 Timothy 1:9, which states that God saved us and called us not according to our works, but according to His own purpose and grace. This reinforces the doctrine that salvation is entirely God's initiative and grace, affirming that it is not something we earn or deserve. According to Romans 3:24, we are justified freely by His grace through the redemption that is in Christ Jesus, illustrating that our salvation is a result of God's grace given to us through faith in Christ.
