Eph 2:4-6
"But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, 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."
The 'but God' (ho de theos) is the most dramatic turn in biblical theology. Three divine actions: made alive, raised, seated — all in the past (aorist), all 'together with Christ' (syn-). The believer's position is 'in the heavenly places' — present, not only future.
Eph 2:8-10
"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. For we are his workmanship, created in Christ Jesus for good works."
The clearest verse about grace in the NT. Salvation is: (1) by grace (chariti); (2) through faith (dia pisteos); (3) a gift of God (theou to doron); (4) not of works. But v. 10 completes: we are created for good works — grace does not eliminate works, it eliminates works as a means of salvation.
