I Timothy 6:6-10 (New International Version)

6But godliness with contentment is great gain. 7For we brought nothing into the world, and we can take nothing out of it. 8But if we have food and clothing, we will be content with that. 9People who want to get rich fall into temptation and a trap and into many foolish and harmful desires that plunge men into ruin and destruction. 10For the love of money is a root of all kinds of evil. Some people, eager for money, have wandered from the faith and pierced themselves with many griefs.

Matthew 16:24-26 (New International Version)

 24Then Jesus said to his disciples, "If anyone would come after me, he must deny himself and take up his cross and follow me. 25For whoever wants to save his life[a] will lose it, but whoever loses his life for me will find it. 26What good will it be for a man if he gains the whole world, yet forfeits his soul? Or what can a man give in exchange for his soul?
