And those who make use of the things of the world [should live] as though they were not [really] involved with them. For the world as we know it is passing away. [Note: The five "as though's" of verses 29-31 are intended to emphasize that Christians should live with eternity in mind and not to become preoccupied with even legitimate earthly circumstances].

Your gold and silver have tarnished and their tarnish will be a testimony against you [i.e., you have hoarded your wealth instead of using it to benefit others], and they will devour your flesh as fire [i.e., your riches will ultimately consume you]. You have hoarded up your riches in these last days.
1 Peter 1:24
For all forms of flesh are similar to grass, and all the splendor of [a person's] flesh is like the flower [which blossoms] from the grass. [But as with] grass, [a person's flesh] withers, and its flower [i.e., his splendor] falls off.
1 Peter 5:7
