Great question. I’m so glad I asked! 😀
But seriously, the Trinity is important. Why? Because the question gets at the heart of who God is.
If you consider that the Bible is God’s revelation to us (it’s His story, after all) and what is important to Him, then if we truly want to worship Him we need to understand to the best of our ability who He is. Short answer: know Who you worship.
And the answer to Who you worship is vital. It’s a question of life or death…external glorious life, or eternal fiery death.
Orthodox Christianity (i.e. generally accepted Christianity) believes that God, or more correctly the Godhead, exists eternally in three persons–the Father, Son, and Holy Spirit. All three are distinct, yet the same substance/essence/nature. In other words, the substance/essence/nature is what one is (I’m human), and a person is who one is (I’m Lisa).
Obviously this is a difficult issue to grasp because there isn’t really anything in our world that is distinctly three and yet one at the same time. Can you think of anything? The best I could come up with is a Venn diagram. (Go ahead and laugh). Let’s say you had 3 different colored circles/spheres/globes, whatever. Each circle is a distinct color, and yet all are circles. It is when they overlap and a new color is formed that you get “God.” The thing I like about this metaphor is that all 3 can overlap, but depending on how they are arranged, two or none might overlap as well.
We experience something similar when, as believers, the Holy Spirit comes upon us. It’s not like we end up with a split personality or some alien-parasitic type of relationship. It’s more of a blending of two Spirits. Our different circles overlapping, although in this scenario our circle would be much smaller, and not as round, and paler in comparison.
Clear as mud?
Well, there’s lots more we can talk about on this topic, but I’d like to leave you with the biblical text that proves the Trinity to me.
Jesus to His disciples: Therefore, go and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit. ~Matthew 28:19
If God the Father was the one-and-only God, as the Jehovah’s Witnesses contend, then why would Jesus tell us to baptize in the name (singular) of the Father, Son, and Holy Spirit?
If the Holy Spirit is nothing more than the Almighty God’s force/power, then why mention Him here? Why not just say Father and Son, or just YHWH?
And that’s why I think that God told Moses His name is “I AM that/who/what I AM.” (Exodus 3:14). Because, truly, how can we hope to comprehend God completely?
It is what it is, folks. Just sayin’…
So if Jesus said to baptize in the name of the Father, the Son, and the Holy Spirit, well, that’s good enough for me.
Your thoughts? Is there a specific text or verse that either convinces you of the Trinity or brings it into doubt for you?
