Draw a grid with four quadrants...
The far right side is a really good things. for example- a well written book, a well done movie or play, a fun toy, a fun situation even.
The far left side is a really bad things. for example- a badly written book, a badly done movie or play, a badly made toy or an unsafe situation.
The top is FOR God and the bottom is AGAINST GOD.
Now take a movie for this example. The Lion, the Witch and the Wardrobe. It was a well done movie.. we will give it the highest rating... a five. It is FOR God... it show redemption, forgiveness, truth etc. but since it doesn't actually MENTION salvation (it is an allegory) we will only give it a 4. Now mark on the graph. So this movie is put in the FOR GOD/ really good thing quadrant. You could basically recommend it to anymore.
A movie could be in the really bad side (not well made) but still be FOR God so it would still be great to see. BUT a movie in the bottom badly made and against God you pretty much wouldn't want to see.
Do you get it.
You could use this with your child for a lot of situations and they could help make decisions about certain things by seeing where it fits on the graph! My kids are visual and especially Matt I think would really like this.
