There is already this decent post: What is the argument *for* prosperity gospel? But more specifically how do prosperity theologians square what must be regular 'clobber' passages for their interpretation?
Do not store up for yourselves treasures on earth, where moths and vermin destroy, and where thieves break in and steal. But store up for yourselves treasures in heaven, where moths and vermin do not destroy, and where thieves do not break in and steal. For where your treasure is, there your heart will be also.
Matthew 6:19-21 (NIV)
Looking at his disciples, he said:
“Blessed are you who are poor,
for yours is the kingdom of God.
Blessed are you who hunger now,
for you will be satisfied.
Blessed are you who weep now,
for you will laugh.
Blessed are you when people hate you,
when they exclude you and insult you
and reject your name as evil,
because of the Son of Man.
“Rejoice in that day and leap for joy, because great is your reward in heaven. For that is how their ancestors treated the prophets.
“But woe to you who are rich,
for you have already received your comfort.
Woe to you who are well fed now,
for you will go hungry.
Woe to you who laugh now,
for you will mourn and weep.
Woe to you when everyone speaks well of you,
for that is how their ancestors treated the false prophets.
Luke 6:20-26 (NIV)
