But I still think it is a helpful way to relate individual verses to the very broad doctrine of the Trinity. Continuing to soak in this watery illustration, you might wonder where we should begin our investigation. Don't dismiss this discussion simply on the basis of terms which might be unfamiliar to you. While the terms themselves might be unfamiliar, I guarantee that you use both induction and deduction every single day. Let me explain.
Induction is the process of observing particular details and noting that the outcome is consistent.
Based on this repeatability, induction concludes that to repeat those details again will, in all likelihood, give the same result. That's not by chance. To use an illustration you will be familiar with, let's think about playing catch with a ball. Every time you play catch, you are using inductive reasoning. Based on your previous experiences playing catch, you expect the ball to come back to earth after you throw it.
