God is giving a new gift: his Holy Spirit will fill his people abundantly. The Spirit who filled prophets, priests, and kings so they could perform their special task, is now going to fill everyone personally! The boundlessness that Moses yearned for will one day break forth (Numbers 12:6, see also Numbers 11:29). No one is too young or too old to receive this Spirit. Even adolescents receive this Spirit. There is no difference at this point between men and women. Male and female slaves also receive God’s Spirit (Galatians 3:28). In fact, God already abolishes slavery here. The people should start looking and listening respectfully also to the servants. God’s Spirit can say something to his people also through them.
28 Après cela, je répandrai mon Esprit sur toute chair; Vos fils et vos filles prophétiseront, Vos vieillards auront des songes, Et vos jeunes gens des visions.
