Virtue or Vice?

Where is the line between virtue and vice? It's sometimes difficult to determine when a virtue has turned into a vice. However, every virtue must be seasoned with temperance or it may become a vice.

The following list is presented to illustrate where the line is crossed.

Christians should be:

self-reliant—but not self-sufficient

energetic—but not self-seeking

firm—but not dogmatic

steadfast—but not stubborn

tactful—but not timid

serious—but not sullen

loyal—but not sectarian

tenderhearted—but not touchy

disciplined—but not cloned

meek—but not spineless

humorous—but not a buffoon

concerned—but not a busybody

holy—but not "holier-than-thou"
