Grace is not earned.
If grace could be earned, then it is debt and no longer grace.
Romans 11:6 KJV
(6) And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work.
2 Timothy 1:9 KJV
(9) Who hath saved us, and called us with an holy calling,
not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began,
Romans 4:4-5 KJV
(4) Now to him that worketh is the reward not reckoned of grace, but of debt.
(5) But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.
