What are Good Works?
Good works are actions that God wants us to do. Good works do not save us (Eph. 2:9), but if you are saved you will want to do good works. The only works that save a sinner are the works of Jesus Christ. Because of His works, those who are forgiven obey Him because they love Him (John 14:15).
Good works do not save us
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 (Ephesians 2:8-9)
Christians obey Jesus because they love Him
If you love me, you will keep my commandments (John 14:15)
