But ye shall receive power, after that the Holy Ghost is come upon you!
There are other translations that I find helpful in understanding this promise Jesus made to the born again ones.
But you will receive power when the Holy Spirit comes upon you. This says the same thing but expresses it a little differently.
These words were spoken by Jesus to the apostles and possibly some others.
The passage written by Luke in Acts 1:1-14 indicates there were many believers in the area. On the day of Pentecost they all received the Spirit's infilling or baptism and after that they were referred to as being Anointed.
Acts 10:38 speaks of the anointing Jesus had;
"You know what has happened throughout the province of Judea, beginning in Galilee after the baptism that John preached--how God anointed Jesus of Nazareth with the Holy Spirit and power, and how he went around doing good and healing all who were under the power of the devil, because God was with him."
There are two things mention here and perhaps we should read it a bit more carefully. Jesus was anointed with the Holy Spirit and power. This is all conjecture on my part but the scripture declares the believer is anointed;
1 John 2:20 "But you have an anointing from the Holy One, and all of you know the truth."
But in everyday life the power seems to be missing. When we come face to face with a situation we need both the anointing and the power and we need to know we have both.
We need this assurance in order to pray with authority. If you find yourself questioning your ability to get answers when you pray then it should help to understand the anointing you have as a believer.
