Each branch of a vine is bound to a certain point of its wall or its conservatory. It is not growing just where and how it would spontaneously and naturally choose, but is affixt there contrary to its natural bent, in order that it may catch the sunbeams at that point and cover that spot with beautiful foliage and luscious fruit.
Sorrow is like the nail that compels the branch to grow in that direction; inevitable circumstance is like the rough strip of fiber which bends the branch, and pain is like the restraint which is suffered by the branch which would have liked to wander at its own will. We are not to murmur or repine at our lot in life, but are to remember that God has appointed it and placed us there.
"To every thing there is a season, and a time to every purpose under the heaven" Ecclesiastes 3:1
