39 This promise is to you, to your children, and to those far away—all who have been called by the Lord our God.
— Acts 2:39 NLT
The disciples had been through basic training and spent three years with Jesus. They had peen patient, prayerful and persecuted and they had persevered through it all. True, they had their moments of doubts and disappointments and had at one point run away and left Jesus all alone to face his killers. But when the time was right, Jesus had brought them all back together and given them their final instructions before His departure. The first instruction was to “wait in Jerusalem”. The basic training was over and they were about to go on their first missions without Him as their leader. Up to now, the provisions and power had come through Jesus but He was no longer physically with them. Now, the time had come for them to tap into the source of power through another person, the Holy Spirit. A person just as much as Jesus, in fact, the same person but not in human form. Jesus was God in visible human form. The Holy Spirit is the new heart-sized version, just as powerful and able to be everywhere at once.
The disciples now had the power and God would give them the provisions. The fight was on, the Commander had given the order– “Charge!” and the power started a great movement that is still alive today. We are the “far away” mentioned in this verse. It is up to us to be the hands and feet as the Holy Spirit carries on the battle.
