Fruitology is a theological exposition of the conceptology of fruits in the Bible in relation to the cosmological effect it has got on the humanity. The word Fruit is a form of reward for service and it is the good results of an activity or a situation. Suffice to say that the fruit generally performs four major functions. These Functions are Identification, Authentication, Differentiation and Distinguish. So, the fruit of a tree identifies the tree, differentiates the tree from other similar tree, project the tree as the authentic producer of the fruit and more importantly distinguish the tree from others. The message of the book is centered on how fruitfulness applies both to plant and animal respectively. Reading through, you will discover six levels of fruitfulness in man as it applies to dominion mandate and discipleship mandate. The fruit is to be eating. However, the sustainability and continuity of life both in plant and animal otherwise called seed is in it. Hence, in every fruit, there is a seed.
