Ephesians 2:8-10  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.

Titus 3:5 & 8  Not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit,… This is a faithful saying, and these things I want you to affirm constantly, that those who have believed in God should be careful to maintain good works.  These things are good and profitable to men.
