For through him we both have access in one Spirit to the Father. So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, in whom the whole structure, being joined together, grows into a holy temple in the Lord. In him you also are being built together into a dwelling place for God by the Spirit.
(Ephesians 2:18-22 ESV)
I believe what Paul says here stands on its own. As believers, saints even, we all have access to the Father through one spirit. We are all built together as a house for God. Sometimes, I know, it feels like it's not us, its all those shiny people, the pastors and teachers, but no, its us, all of us.
And you show that you are a letter from Christ delivered by us, written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts.
(2 Corinthians 3:3 ESV)
And given this knowledge that we are all a dwelling place of the Lord, his beautiful bride, joined into one flesh, Paul also shows us that we are a letter from Christ to others, that Christ has written his signature in your heart with his spirit. We all have some message of Christ to share with others, those among us. Who does? You do, I do, we all do.
What then, brothers? When you come together, each one has a hymn, a lesson, a revelation, a tongue, or an interpretation. Let all things be done for building up. .... Let two or three prophets speak, and let the others weigh what is said. If a revelation is made to another sitting there, let the first be silent. For you can all prophesy one by one, so that all may learn and all be encouraged, and the spirits of prophets are subject to prophets. For God is not a God of confusion but of peace.
(1 Corinthians 14:26-33 ESV)
In this same theme, Paul shows us that when are together, we all have something to contribute, not just your designated leader at the time. How do we know this? because of the above! You are a habitation of Christ, you are a letter from Christ, written on your hearts, from the very core of your being. And why? "Let all things be done for building up." Your message from Christ can build up those around you, yes, you.
Now forgive me if you feel I am stretching this a little too much, but where as I believe some are given the gift of prophesy, I believe that because of the above, because we have the Christ dwelling within us, that he has written his message upon our hearts, we all have the ability to prophecy of Christ, the living Christ that dwells within all of us, to share some aspect of his character, of his love, of his greatness to, those among us.
Interestingly, in ye olde king james english, the letters almost use “ye” to address us, and "ye" isn't "you", an individual, it's Y'ALL, all of us, not a chosen few. All of us.
