Power in the Holy Spirit

Smith Wigglesworth's daughter asked some African boy's one day to tell her the difference between being saved and being filled with the Holy Spirit.

"Ah," they said, "when we were saved, it was very good; but when we received the Holy Spirit, it was more so." Many of you have never received the "more so".

After the Holy Spirit comes upon you, you will have power. God will mightily move within your life' the power of the Holy Spirit will over shadow you, inwardly move in you until you know there is a divine plan different from anything that you have had in your life before.

While Apollos was at Corinth, Paul took the road through the interior and arrived at Ephesus. There he found some disciples and asked them,
"Did you receive the Holy Spirit when you believed?"

They answered, "No, we have not even heard that there is a Holy Spirit."
So Paul asked, "Then what baptism did you receive?"

"John's baptism," they replied.
Paul said, "John's baptism was a baptism of repentance. He told the people to believe in the one coming after him, that is, in Jesus."
On hearing this, they were baptized into the name of the Lord Jesus.
When Paul placed his hands on them, the Holy Spirit came on them, and they spoke in tongues and prophesied.

Acts 19:1-6
