The word Trinity does not appear in the Bible. For that matter, neither does the word Bible. And just like we don’t disassociate the Bible from the Holy Scripture, neither do we dissociate the Trinity from God. The Trinity provides us with a description of the nature of God. The Bible tells us that God, Who is the creator of both the heavens and the earth, is a single being, who is self existing and unchangeable (Isaiah 43:10; 44:6, 8). This means that God is one in essence and one is substance. But in the same manner, the Bible also teaches us that God is three distinct persons as well. He’s God the Father, God the Son, and God the Holy Spirit. Each person is distinct from the other, yet each is identical in essence and fully divine. Granted, this does not mean that there are three Gods. There is only one God. There is only one God Who is manifested is three forms.
This concept of the Trinity can be difficult to understand because it does not seem natural. However, when you begin to understand that God does not have the same nature as humans, but instead He has a super nature, the concept of the Trinity is a litter easier to grasp. He is a supernatural God, Who has demonstrated the ability to do supernatural things and one the supernatural things that God does is exist as three persons in one nature, which is know as the Trinity.
