Matthew 16:18-19 (ESV)
18 And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it.
19 I will give you the keys of the kingdom of heaven,  and whatever you bind on earth shall be bound in heaven, and whatever  you loose on earth shall be loosed in heaven.”

Ephesians 1:19-23 (ESV)
19 and what is the immeasurable greatness of his power toward us who believe, according to the working of his great might
20 that he worked in Christ when he raised him from the dead and seated him at his right hand in the heavenly places,
21 far above all rule and authority and power and  dominion, and above every name that is named, not only in this age but  also in the one to come.
22 And he put all things under his feet and gave him as head over all things to the church,
23 which is his body, the fullness of him who fills all in all.

1 Corinthians 6:2-3 (ESV)
2 Or do you not know that the saints will judge the  world? And if the world is to be judged by you, are you incompetent to  try trivial cases?
3 Do you not know that we are to judge angels? How much more, then, matters pertaining to this life!

Revelation 2:26-27 (ESV)
26 The one who conquers and who keeps my works until the end, to him I will give authority over the nations,
27 and he will rule them with a rod of iron, as when  earthen pots are broken in pieces, even as I myself have received  authority from my Father.

Revelation 3:21 (ESV)
21 The one who conquers, I will grant him to sit with  me on my throne, as I also conquered and sat down with my Father on his  throne.

May the Lord envision our hearts with the glorious authority we have in Christ!

We must learn to pray with authority which looks less like begging on  earth for something from heaven, and more like executing something by  praying from heaven to earth.

Ephesians 2:6 (ESV)
6 and raised us up with him and seated us with him in the heavenly places in Christ Jesus,
