Acts 8:16

for as yet it was fallen upon none of them: only they had been baptized into the name of the Lord Jesus.

'THEY WERE COME DOWN'-'This is the usual language for someone leaving Jerusalem, for this required the traveler to descend ("go down")..Samaria actually is north of Jerusalem, but it is still "down" from Jerusalem.' (Reese p. 323)

'PRAYED FOR THEM'-The distribution of the Spiritual Gifts rested with God (1 Corinthians 12:11).

'SIMPLY BEEN BAPTIZED INTO THE NAME OF THE LORD JESUS'-

Points to Note:

Clearly the baptism mentioned is water baptism. It isn't Holy Spirit baptism, for the Holy Spirit had not fallen on any of them. Notice that water baptism is connected with the name of the Lord Jesus. Proving that water baptism is the baptism of the Great Commission (Matthew 28:19), and the baptism connected with salvation (Mark 16:16; Acts 2:38 'be baptized..IN THE NAME OF JESUS CHRIST UNTO THE REMISSION OF YOUR SINS.'

Here we learn that the gift of the Holy Spirit connected with water baptism, doesn't involve an immediate ability to work miracles or speak in tongues.

And carefully note that the miraculous or direct influence of the Holy Spirit wasn't needed so these people could believe. The idea that man is born depraved, opposed to all good, and cannot even manifest faith apart from the direct operation of the Holy Spirit, doesn't fit these passages. These people heard the gospel, believed it and were baptized, without the Holy Spirit directly operating upon their heart.
