I would like to discuss the various explanations Christians have towards the Trinity and how to effectively explain it to the unbeliever.
God gave me this a few years ago. It is not as complex as most make it out to be. The Father, Son and Holy Spirit are one in Essence, which means what they stand for, or what they are about. But they are three unique individuals in their office, or what their mission is.
All three have equal make-ups in who they are, all three are Love, Hope, Joy, Peace, Long-suffering, Honest, Trustworthy, Caring, etc. etc. they are exactly the same in their essence or make-up. All three are different in their missions or offices. God the Father has the abundance of the Glory, no man can look upon Him, the Holy Spirit can live in us, if God lived in us in His fullness, we would be consumed by His Glory, Jesus walked the earth, so he doesn't have the fullness of Gods glory either, but he is God in essence, just not the fullness of God the Father.
Here's an example God gave me. Take a Three Trillion Gallon reservoir of water, it has the exact same make-up throughout, it has the exact same chemical make-up in all three trillion gallons of water, the essence of every gallon is the same. Now Pour 100 (Jesus) gallons over your head, you will be soaking wet, but OK. Now pour another 100 (Holy Spirit) gallons over your head, again you will be soaked but OK no doubt. Now take the Full Three Trillion (God the Father) Gallons of water and pour it over your head and you will surely drown NO DOUBT, in other words, the Fullness of the Glory lies with God the Father, Jesus and the Holy Spirit are exactly the same in what they stand for, but not exactly the same in the ABUNDANCE OF GLORY.
Three in one, all three the same but different.
