Read Prosperity Preaching: Deceitful and Deadly, by John Piper, at One Place.
"What will make the world taste (the salt) and see (the light of Christ in us is not that we love wealth the same way they do. Rather, it will be the willingness and the ability of Christians to love others through suffering, all the while rejoicing because their reward is in heaven with Jesus. This is inexplicable on human terms. This is supernatural. But to attract people with promises of prosperity is simply natural. It is not the message of Jesus. It is not what he died to achieve."
"So then, none of you can be My disciple who does not give up all his own possessions.
And Jesus, looking around, said to His disciples, "How hard it will be for those who are wealthy to enter the kingdom of God!" The disciples were amazed at His words. But Jesus answered again and said to them, "Children, how hard it is to enter the kingdom of God! "It is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God." They were even more astonished and said to Him, "Then who can be saved?" Looking at them, Jesus said, "With people it is impossible, but not with God; for all things are possible with God."
But godliness actually is a means of great gain when accompanied by contentment. For we have brought nothing into the world, so we cannot take anything out of it either. If we have food and covering, with these we shall be content. But those who want to get rich fall into temptation and a snare and many foolish and harmful desires which plunge men into ruin and destruction. For the love of money is a root of all sorts of evil, and some by longing for it have wandered away from the faith and pierced themselves with many griefs.
1 Timothy 6:6-10
"Do not store up for yourselves treasures on earth, where moth and rust destroy, and where thieves break in and steal."
He who steals must steal no longer; but rather he must labor, performing with his own hands what is good, so that he will have something to share with one who has need.
Make sure that your character is free from the love of money, being content with what you have ; for He Himself has said, "I WILL NEVER DESERT YOU, NOR WILL I EVER FORSAKE YOU," so that we confidently say, "THE LORD IS MY HELPER, I WILL NOT BE AFRAID. WHAT WILL MAN DO TO ME?"
"The seed which fell among the thorns, these are the ones who have heard, and as they go on their way they are choked with worries and riches and pleasures of this life, and bring no fruit to maturity.
"Blessed are you when people insult you and persecute you, and falsely say all kinds of evil against you because of Me. "Rejoice and be glad, for your reward in heaven is great; for in the same way they persecuted the prophets who were before you.
