Two Oxen.

In ourselves, true Christians have 'a worldly tendency' with traces of our 'old nature' before coming to Jesus, in evidence.
We also have our distinct and positive spiritual side.
Which will prevail?

Imagine this in terms of two oxen - pound for pound probably as strong as any mammal on the planet each working against the other.
Which ox will overcome in our lives?
Simple - the one we feed!
(Don't know who the preacher was who gave this illustration - but it is pretty sound.)
