Acts 8

 Therefore those who were scattered went everywhere preaching the word...Now when the apostles who were at Jerusalem heard that Samaria had received the word of God, they sent Peter and John to them,   who, when they had come down, prayed for them that they might receive the Holy Spirit.   For as yet He had fallen upon none of them. They had only been baptized in the name of the Lord Jesus. vv.4,14-16

Read chapter 8
The great scattering.  We just saw Stephen martyred and the result seems to be that every believer was encouraged and spread out preaching the Word of God.  Opposite of what Satan and the evil leaders thought would happen.  Many became believers because of this for as the word was preached to them and they believed it they became baptized in the Lord Jesus.  We notice from this passage that there's a difference in baptism of the Holy Spirit.  Not just anyone could baptize a person in the Holy Spirit but the apostles alone.  Just as we see here Simon the Sorcerer wanting that power to baptize others in the Holy Spirit so many believers today try to take that authority that isn't' for them.  And just as Simon couldn't figure out the "trick" neither does baptism of the Holy Spirit practiced today look anything like what we see baptism of the Holy Spirit in scripture.  Oh bring the day through when we will be baptized with signs following (Mark 16).
