And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit, who is a deposit guaranteeing our inheritance until the redemption of those who are God’s possession—to the praise of his glory. Ephesians 1:13-14 (NIV)
Hatun talks about how each member of the Trinity functions in the process of our salvation according to the Apostle Paul. Salvation is a gift from God, something for which we cannot work.
