My take on Luke 9 is as follows: I believe it to be a blueprint for the advancing of the Body of Christ at the end of the age. I believe it gives the roadmap of the necessary preparation for us to go from "the 12" to "the 70". In other words, to really enter in to the day of the saints and not simply the day of the few on their platforms.
Look at the amazing preparation and progression that goes on here. The 12 disciples finally become apostles in Luke 9. They are truly "sent ones" by Jesus, (Luke 9:1). They have been marinating in the message of the Kingdom for some time, since their "Intro to the Kingdom" class at the Sermon on the Mount (Luke 6). They've been watching Jesus for many weeks, maybe months (cf. Luke 8:1 "... He went through every city and village preaching and bringing the glad tidings of the Kingdom..." "...and the twelve were with Him...") and now they take their ministry out for a test drive (so to speak): "...they departed and went through the towns, preaching the gospel and healing everywhere," (Luke 9:6).
When they come back Jesus takes them aside for further teaching, a small private conference with just He and them (verse 10). It gets blown up by the hunger of the other people following Jesus as they press in as well; He does not turn them away but uses this as a context to show His disciples that God is able to feed those that come to Him. I think it was getting deeply ingrained in them to become people of prayer and dependence upon Him as He lets them feel their lack ("You give them something to eat") and shows them the means by which God will provide ("... looking up to heaven, He blessed and broke them..."). This is what I believe He was doing with the 12 just like he did with that bread, so that the "day of the saints" would come about (in a small way for them, in a larger way for us now at the end of the age): 1) He prays for them and asks that their destiny in God be accomplished, 2) He blesses them with anointing for multiplication, 3) He breaks them so they can be given away and poured out.
The preparation for the remarkable release of the 70 in Luke 10 (Satan being cast down) requires several things being touched upon and broken in these burgeoning leaders. You will see more than I'll note here but here are among the highlights:
1) there is revelation of Jesus' nature,
2) there is confirmation of their basic message to come: Jesus MUST die
3) He emphasizes the price is high, costing everything
4) their personal ambition is addressed and corrected (note: after their "solo flight" they were comparing stories and arguing who was the greatest among them, (vv. 46ff).
He then releases the 70 as strongholds have at that point been both torn down or added to them for the way ahead. And so when they return, Jesus is ecstatic at the impact it had on the region: Satan fell like lightning from heaven! Brother, this was BEFORE THE CROSS! This was while they were yet unable to appropriate HIS BLOOD! We have great challenges and breakthroughs ahead for us as the people of God. The day of the saints is at hand! Who will deal with these strongholds and come out meek on the far side of them? The Lord is preparing a great and mighty army, He is not slack to prepare His church for the day ahead and it will be with leaders such as these. Amen? Amen!
24 hour prayer and worship very much becomes the hub of the Christian community in days to come. The harvest is connected to it, but thats another emphasis for another letter.
Now to Him who is able to keep you from stumbling,
And to present you faultless
Before the presence of His glory with exceeding joy,
To God our Savior,
Who alone is wise,
Be glory and majesty,
Dominion and power,
Both now and forever.
Grace to you. I love you.
