Choice, not chance, determines destiny. The Law of Sowing and Reaping The law of sowing and reaping is the first of the universal laws. It is the law of cause and effect. Whatever you sow and plant in the garden will produce a crop. For every cause, there is a corresponding effect. Use this law to your advantage. You are going to manage what you sow and you are going to manage what you reap. What you sow is a cause, what you reap is an effect.
