We are saved by grace. Not by what we have done or haven’t done. Only by God’s grace. There are no works that one has to achieve when God is who gives grace.
 
For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
Ephesians 2:8-10
