Benefits of the Holy Spirit

When I think of the Holy Spirit I think of things like guidance and revelation.  Not sure how I missed this.  In Acts Jesus tells us that we receive power when we receive the Holy Spirit. 

But power for what?  My guess is it is power to accomplish the life's work that God gives us.  Scripture tells us that when God gives us work He also gives us the tools to complete that work. 

Acts 1:4-8(NKJV)

And being assembled together with them, He commanded them not to depart from Jerusalem, but to wait for the Promise of the Father, “which,” He said, “you have heard from Me; 

for John truly baptized with water, but you shall be baptized with the Holy Spirit not many days from now.” 

Therefore, when they had come together, they asked Him, saying, “Lord, will You at this time restore the kingdom to Israel?” 

And He said to them, “It is not for you to know times or seasons which the Father has put in His own authority. 

But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth.”
