By Their Fruits...

Matthew 7:20
"Wherefore by their fruits ye shall know them."

“And whatsoever thing persuadeth men to do good is of me; for good cometh of none save it be of me. I am the same that leadeth men to all good.” (Ether 4:12)

"Intelligence is the ability to use knowledge properly"
- Elder Royden G. Derrick

We make choices every day. We look at the output or results of something, and decide if it's worth it.
We look at a potential apartment, and if there is mold all over the walls, and the carpet smells weird, we don't buy it.  If we find a nice, clean apartment with good reviews, we decide to look into it further.

If only we would use this more with our gospel decisions. If we would look at the movies we are watching, realize the effects they could have on our minds, and realize the rampant problem of pornography around us, we might reconsider just fast-forwarding through the "bad parts."
If we found a cockroach baked into a cake, we wouldn't just eat around it, we would probably throw it away.

Look at the results.

Jacob 6:12 " O be wise; what can I say more?"
