Before I try to explain an infinite God with my finite brain, I will bring this verse to mind: Proverbs 3:5-7 states, ''Trust in the Lord with all your heart and lean not on your own understanding; in all your ways acknowledge Him, and he will make your paths straight. Do not be wise in your own eyes; fear the Lord and shun evil." So, with this in mind, I will attempt to explain the Trinity.
The best way to explain the Trinity is not with a statement, but with a question. If l were to take an egg, and crack the shell in half, and then use a strainer to separate the white and the yoke, then, if I set all three parts down separately on the counter, there would be three different things, with three completely unique characteristics. The shell is the protective coat, the white is the nutrition for the growing chicken, and the yoke is the thick protein substance that becomes the chicken. The question, then, is: Which one is the egg?
Most people would probably want to say. "Well, the yoke is the most important, and therefore it is the egg." However, it is not the most important, because all three are essential to bringing life. Without the yoke there could be no chicken. Without the white, it could never survive, and without the shell, it is breakfast. So then, the egg is all three put into one. There is only one egg, but it consists of three parts. I believe that examples such as the egg, and other examples such as electrons, protons, and neutrons, reveal the characteristics of God Almighty. The properties found throughout the Universe in Quantum Physics, etc., show that things are consistently made of sets of three--the very substance of our matter, things smaller than electrons, protons, and neutrons are built on sets of three. I and many others believe that these attributes are all the fingerprint of God, revealing His divine characteristics. Paul even before we saw such evidences in nature said:
For since the creation of...
