“In Him, you also, after listening to the message of truth, the gospel of your salvation—having also believed, you were sealed in Him with the Holy Spirit of promise” (Ephesians 1:13).
Upon conversion, as scripture describes in various ways, we received the gift of the Spirit. We were filled with the Spirit. Baptized by the Spirit. Sealed by the Spirit. Indwelled by the Holy Spirit. Instead of debating these as separate actions to be experienced at different times, they are best understood as reminders of the supernatural phenomenon of salvation that has been and is being accomplished in us. It’s not something that can be manipulated by man or institutionalized by the church but is a miraculous act of God.
