The work of the Triune God is obvious at every important point of history: creation, incarnation, resurrection, and also Pentecost. Exalted by the Father (v. 33), Christ poured out His Spirit (v. 33), and the Spirit testified of Christ (v. 31) while the Lord added to the church (v. 47). Blessed be the triune God (Eph. 1:3).
