Satan told Jesus,
“I will give you all their authority and splendor; it has been given to me, and I can give it to anyone I want to. If you worship me, it will all be yours.” (Luke 4:6-7)

After Jesus’ resurrection and defeat of Satan (triumphing over Satan) Jesus says,
“All authority has been given to Me in heaven and on earth. Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,  teaching them to observe all things that I have commanded you. (Matthew 28:19-20)

Jesus uses His authority to endow His followers with miraculous power by the baptism of the Spirit.

“And now I will send the Holy Spirit, just as my Father promised. But stay here in the city until the Holy Spirit comes and fills you with power from heaven.” (Luke 24:49)

““Do not leave Jerusalem, but wait for the gift my Father promised, which you have heard me speak about.  For John baptized with water, but in a few days you will be baptized with the Holy Spirit.” you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.”
(Acts 1:4,8)

“When Jesus had called the Twelve together, he gave them power and authority to drive out all demons and to cure diseases, and he sent them out to proclaim the kingdom of God and to heal the sick.” (Luke 9:1-2)

If this was true, before the resurrection and before Jesus had sat down at the right hand of power, and all authority given to him both in heaven and earth, then how much more do we have authority and power to drive out demons, heal the sick and proclaim the Kingdom today!

Then Peter said, “Silver or gold I do not have, but what I do have I give you. In the name of Jesus Christ of Nazareth, walk.” (Acts 3:6)
