Instead of waiting for God to do what God is sure to do, they try to do it themselves. Instead of waiting with the carefree attitude of children who truly trust their Father in heaven, they scurry about with spiritual agitation and religious maneuvering to accomplish what they are afraid God will not. This interpretation of the parable says that we should not to anything, therefore, but just leave it all up to God. There are some valid points in such an interpretation, passivity is exaggerated. The problem in a lot of churches is not with people doing too much, but too little.
Congregations are often rich with advisors but impoverished when it comes to workers.
That isn't how I read the parable at all. The point Jesus is making is not that we are to do nothing, but rather that we are to know the difference between what we are to do and what we are to leave up to God to do. Remember, the man in the parable did not do nothing. He sowed the seed. He slept during the night and rose up the next morning and went about his normal work in other areas of his life.
