what do we really need

What do we need to be disciples?  What is sufficiency as an apostle?  These two passages below make it clear that we don't need much.  What we need most of all is to rely on God on this journey.  I wonder as I look at a lot of church buildings and the homes that a lot of American Christians live in how we reconcile these passages with what we think we need today to live.  And are we more concerned about our living or serving God as indicated in these passages? Luke 9  1Jesus called together his twelve apostles and gave them complete power over all demons and diseases. 2Then he sent them to tell about God's kingdom and to heal the sick. 3He told them, "Don't take anything with you! Don't take a walking stick or a traveling bag or food or money or even a change of clothes. 4When you are welcomed into a home, stay there until you leave that town. 5If people won't welcome you, leave the town and shake the dust from your feet as a warning to them." 6The apostles left and went from village to village, telling the good news and healing people everywhere. Luke 10  1Later the Lord chose seventy-two other followers and sent them out two by two to every town and village where he was about to go. 2He said to them: A large crop is in the fields, but there are only a few workers. Ask the Lord in charge of the harvest to send out workers to bring it in. 3Now go, but remember, I am sending you like lambs into a pack of wolves. 4Don't take along a moneybag or a traveling bag or sandals. And don't waste time greeting people on the road. 5As soon as you enter a home, say, "God bless this home with peace." 6If the people living there are peace-loving, your prayer for peace will bless them. But if they are not peace-loving, your prayer will return to you. 7Stay with the same family, eating and drinking whatever they give you, because workers are worth what they earn. Don't move around from house to house. 8If the people of a town welcome you, eat whatever they offer. 9Heal their sick and say, "God's kingdom will soon be here!" 10But if the people of a town refuse to welcome you, go out into the street and say, 11"We are shaking the dust from our feet as a warning to you. And you can be sure that God's kingdom will soon be here!" 12I tell you that on the day of judgment the people of Sodom will get off easier than the people of that town!
