According to Parkinson and Bates, Production is defined as an organized activity of transforming resources into finished products in the form of goods and services.

From the above definition, the objective of production is therefore to satisfy the demand for goods and services.

It is worthy of note to state that whenever services are rendered, such rendered services are also considered as production. This is true because the rendered services satisfy the needs or wants of the recipient or consumer.

Therefore, people who provide services like hairdressers, security men and public bus drivers are considered productive; and whatever service had been rendered can appropriately be referred to as production.

Now the snake was the most cunning animal that the Lord God had made. The snake asked the woman, 'Did God really tell you not to eat fruit from any tree in the garden?'

Genesis 3:1

Moral Lesson: The devil can come in any form and can tempt any man, woman, boy or girl, as far as he or she is of the age of reasoning.

Sometimes, satan creeps into one's life by asking simple questions. Notice that the snake (satan) did exactly this when it approached Eve to tempt her. To this end, we need to be at alert prayerfully because the evil one can tempt any human in any situation, place and at any point in time
