And you were dead in your trespasses and sins, in which you formerly walked according to the course of this world, according to the prince of the power of the air, of the spirit that is now working in the sons of disobedience. Among them we too all formerly lived in the lusts of our flesh, indulging the desires of the flesh and of the mind, and were by nature children of wrath, even as the rest. But God, being rich in mercy, because of His great love with which He loved us, even when we were dead in our transgressions, made us alive together with Christ (by grace you have been saved), and raised us up with Him, and seated us with Him in the heavenly places in Christ Jesus, so that in the ages to come He might show the surpassing riches of His grace in kindness toward us in Christ Jesus. For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; not as a result of works, so that no one may boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them. (Ephesians 2:1-9)
Now, would Paul really need to point out that grace was not of ourselves?
No - faith is not of ourselves - it is a gift of God. He gave it to us while we were dead in sins.
"I was blind, but now I see!"
When you're blind, can you make yourself see? No, God must put His grace upon you first.
In the same way, when you're dead you can't make yourself alive - Christ must make you alive. God must make you alive in Christ.
