The skin of an apple will vary in texture, thickness, color, and taste based upon growing conditions such as: soil, temperature, length of growing time, exposure to light and nutrients, proximity to other trees of the same or different fruits, and many other factors too numerous to list. Just like layers to an apple there are layers to all relationships of this world. There are layers with every husband and wife, parent and son, teacher and student, boss and employee, and yes there are even layers within the relationship between the creator and the created. I cannot give you the answers to all the questions in the opening paragraph but as you pull back the flesh of the fruit within your relationship with the creator and taste of its meat and continue to dig deeper into the layers provided these answers will be revealed unto you.
