(**apologies for the poor audio quality this session) Even after His resurrection, Jesus teaches His followers about the kingdom of God. And He does so "through the Holy Spirit". If the glorified & resurrected Son of God relied on the Holy Spirit in communicating Gospel truths, so should we. Everything done in the book of Acts is done this same way - through the Spirit. Knowing the times and seasons of some things isn't a disciples' business - doing and teaching everything Jesus commanded is their business, and they only accomplish it through the Spirit. Jesus explains and clarifies that His mission and kingdom is global, and that the Helper will come to empower Christians to do what He's commissioned them to do.
