When that hand meets a locus of resistance - a knot - it will be removed with a great tearing and painful force. But it will produce a purer work, one without spot or blemish. The aim that it would result in a masterpiece perfectly suited to the purpose for which it was created. The determination of that aim is upon us. If there is an ultimate yielding then the aim is accomplished. If not, the rending is complete and cannot be repaired.
Yield while you can to the kindness of God and remember that his hand is strong but gentle. His force is measured to the resistance.
Don't forget ... it takes practice to perfect artistry.
