But when the Father sends the Counselor as My representative–and by the Counselor I mean the Holy Spirit–He will teach you everything and will remind you of everything I Myself have told you. –John 14:26 (NLT)
Jesus Christ was an amazing example for the disciples to follow as they learned how to be on mission to tell the world about the grace and love of Jesus Christ. As Jesus ascended into heaven, He told the disciples to wait for the Holy Spirit to come over them because Jesus knew that the Spirit would serve as a guide and a teacher in His physical absence.
During the Jewish feast of Pentecost, the disciples got what they were waiting for. The Holy Spirit, the presence of God Himself, took up residence inside ordinary bodies – their bodies. The disciples immediately hit the streets with a bold new style that the world has never recovered from.
