All around us, the structure of nature proclaims the Trinity. There are many more examples I could cite, but I chose the basic things without which there is no life—things like water and matter itself.
Of course, the purpose of these examples is not to prove the doctrine of the Trinity. No, God is too high to be measured or proven by anything. But the purpose is to point out that if God revealed to us that He is a Trinity, we must acknowledge that this concept is consistent with the natural world we see around us.
The Holy Injil clearly declares that God’s invisible qualities—His eternal power and divine nature—have been clearly seen through His Creation, “Since what may be known about God is plain to them, because God has made it plain to them. For since the creation of the world God’s invisible qualities—His eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse. For although they knew God, they neither glorified Him as God nor gave thanks to Him, but their thinking became futile and their foolish hearts were darkened” (Romans 1: 19-21).
There is one God—Father, Son, and Holy Spirit, a unity of three co-eternal Persons. God is immortal, all-powerful, all-knowing, above all, and ever present. He is infinite and beyond human comprehension, yet known through His self-revelation. He is forever worthy of worship, adoration and service by all of creation. (Deuteronomy 6:4; Matthew 28:19; 2 Corinthians 13:14; Ephesians 4:4-6; 1 Peter 1:2; 1 Timothy 1:17; Revelation 14:7.)
