For it is by grace you have been saved, through faith – and this is not from yourselves, it is the gift of God – (NIV)

For it is by free grace (God's unmerited favor) that you are saved (delivered from judgment and made partakers of Christ's salvation) through [your] faith. And this [salvation] is not of yourselves [of your own doing, it came not through your own striving], but it is the gift of God (AMP)

For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: (KJV)
