Eph 2:10.
Again...context is key.
Ephesians 2:8-10 For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; 9not as a result of works, so that no one may boast. 10For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them
So men are saved by grace alone. Faith is the process through which we receive grace. Grace is not of works; all glory in your salvation belongs to God. Good works are necessary because God prepared them for you. This is how you are saved.
