The former account I made, O Theophilus, of all that Jesus began both to do and teach,  until the day in which He was taken up, after He through the Holy Spirit had given commandments to the apostles whom He had chosen, to whom He also presented Himself alive after His suffering by many infallible proofs, being seen by them during forty days and speaking of the things pertaining to the kingdom of God. 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. ⁸ “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.” (Act 1:1-8 NKJ)

“And it shall come to pass afterward That I will pour out My Spirit on all flesh; Your sons and your daughters shall prophesy, Your old men shall dream dreams, Your young men shall see visions.  And also on My menservants and on My maidservants, I will pour out My Spirit in those days”. (Joe 2:28-29 NKJ)

But as many as received Him, to them He gave the right to become children of God, to those who believe in His name: (Joh 1:12 NKJ)

I’ve heard the Greek word for power dunamis translated time and time again as ‘dynamite.’ Actually, the word dynamite was the name given to it by its Swedish inventor, Alfred Noble from the Swedish word dynamit—power.  Dunamis actually comes from the Greek root dunamai meaning ‘can do.’ Can do what?  Well, their question to Jesus was, “”Lord, will You at this time restore the kingdom to Israel?”  Jesus’ indirect response was no, but as the ‘can do’ people you will establish the Kingdom of God here on earth as you bear witness to Word and deed not just here in Jerusalem but all over the world.  The power comes from the Holy Spirit, but the authority to use that power comes because you’re in a relationship with the Father and a child of God (Jn 1:12)

Remember Paul’s exhortation, “ I can do all things through Christ who strengthens me (with the Holy Spirit). (Phi 4:13 NKJ)
