The difference between a smooth and a rough yoke

[marcusampe]

"Did you ever stop to ask what a yoke is really for? Is it to be a burden to the animal which wears it? It is just the opposite: it is to make its burden light. Attached to the oxen in any other way than by a yoke, the plow would be intolerable; worked by means of a yoke, it is light.
A yoke is not an instrument of torture; it is an instrument of mercy. It is not a malicious contrivance for making work hard; it is a gentle device to make hard labor light. [Christ] knew the difference between a smooth yoke and a rough one, a bad fit and a good one... The rough yoke galled, and the burden was heavy; the smooth yoke caused no pain, and the load was lightly drawn. The badly fitted harness was a misery; the well fitted collar was "easy". And what was the "burden"? It was not some special burden laid upon the Christian, some unique infliction that they alone must bear. It was what all men bear: it was simply life, human life itself, the general burden of life which all must carry with them from the cradle to the grave. Christ saw that men took life painfully. To some it was a weariness, to others failure, to many a tragedy, to all a struggle and a pain. How to carry this burden of life had been the whole world's problem.

And here is Christ's solution: "Carry it as I do. Take life as I take it. Look at it from my point of view. Interpret it upon my principles. Take my yoke and learn of me, and you will find it easy. For my yoke is easy, sits right upon the shoulders, and therefore my burden is light.""
