Ephesians 2:8-9
For it is by grace you have been saved, through faith – and this not from yourselves, it is the gift of God – not by works, so that no one can boast.
Romans 8:9-11
You, however, are controlled not by the sinful nature but by the Spirit, if the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, he does not belong to Christ. But if Christ is in you, your body is dead because of sin, yet your spirit is alive because of righteousness. And if the Spirit of Him who raised Jesus from the dead is living in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit, who lives in you.
2 Corinthians 3:18
And we, who with unveiled faces all reflect the Lord’s glory, are being transformed into His likeness with ever-increasing glory, which comes from the Lord, who is the Spirit.
