Luke 16:11
If therefore you have not been trustworthy in worldly wealth, who will put you in charge of the true [spiritual] riches?
Luke 12:33
Sell your possessions and give [the money] to poor people; provide yourselves with money belts that do not wear out [i.e., from the constant use of carrying much money all the time, instead of investing it in others' needs]. [Then you will possess] an inexhaustible treasure in heaven, where no thief can approach, nor moth destroy.
Luke 16:9
Therefore, I tell you, make friends for yourselves by using worldly wealth, so that when it fails [i.e., when you run out of money] they [i.e., the friends you made with its wise and benevolent use] may welcome you into the eternal [i.e., heavenly] dwelling places. [Note: The idea here seems to be that by your shrewd use of material possessions for the benefit of others, you are actually storing up treasures for yourself in heaven].
Luke 18:22
When Jesus heard this He said to him, " [There is] one thing you still lack. Sell all your possessions and distribute [the money] to poor people; become my follower, [then] you will have treasure in heaven."
Ephesians 3:8
This favor of preaching the unfathomable riches of Christ to the Gentiles was given to me [even though] I am the least significant of all saints [i.e., God's holy people].
James 2:5
Listen, my dearly loved brothers; did not God choose those who are poor in the eyes of the world to be wealthy in faith and to inherit the kingdom which He promised to those who love Him?
Revelation 3:18
[Because of that], I advise you to buy from me gold, refined by fire, so that you will become rich; and white clothing to wear, so that you can cover yourself and not be seen as shamefully naked; and eye drops for your eyes, so that you can see. [Note: The foregoing all refer to taking measures for becoming more spiritual].
