With the outpouring of the Spirit on the Day of Pentecost, the blessings for all nations promised to Abraham commenced.
The gift of the Holy Spirit is described as “the promise of the Father” in the New Testament, which connects this gift to the Abrahamic covenant. The promises to Abraham and his seed are fulfilled in the New Covenant inaugurated by the death and resurrection of Jesus Christ, and the gift of the Spirit is the guarantee that we will inherit all that God has promised.
