Interesting and Hidden Aspects:
Light and darkness are the Greek metaphors for knowledge and ignorance.
The Greek verb "to have" has a more physical meaning of holding in your possession than the English word.
The Greek word translated as "believe" has more of a sense of trusting words than than the English word. Here, the sense is trusting in the knowledge one is holding.
The Greek verb translated in the KJV as "may have" is the verb of becoming and it is in many ways the opposite of the verb of being. It indicates a state of change rather than stasis as the verb "to be" does. This verb indicates the creation of something. It means "to be produced" as well as "to become." This verb is in the subjunctive voice indicating that is something that can potential happen or is expected to happen. It is also in the aorist tense, indicating something that happens as a specific point in time.
For Christ, ideas and information produce offspring, that is, more ideas based on the old ones, in the same way that people produce offspring. Ideas are passed down from generation to generation as surely as genes are.
