Before he left his disciples and ascended to heaven, Jesus promised to send his Holy Spirit to enliven their faith, to give them wisdom, and to console them in times of need. And from that point on, believers have come to understand that we all need the Holy Spirit to live out our faith and to be the Lord’s witness. In fact, we could easily expand on Paul’s famous quote from Ephesians 2:4 and say, "He who made us alive by the resurrection now keeps us alive by the power of the Holy Spirit."
