Fruitful in Christ

Beware of the Little Foxes
You could be fruitful but if you don't pay attention to fox, he can destroy the fruit.

Song of Solomon 2:15 — Take us the foxes, the little foxes, that spoil the vines: for our vines have tender grapes.

The devil is a fox

The Devil Is A Sly Old Fox, 
If I Could Catch Him 
I'd Put Him In A Box 
Lock The Box And Throw Away The Key 
For All Those Tricks He's Played On Me. 
I'm Glad I am a Christian (3x's) 
I'm Trusting In The Lord.
