For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should 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

We are not saved by works, but once we are saved, the indwelling Holy Spirit empowers us to fulfill our calling and enables us do the works that God has prepared for us.
