Trinity can be thought of as “three in one.” It is used to reflect the nature of God. There is one God, with three distinct parts: the Father (creator), the Son, Jesus (savior), and the Holy Spirit (counselor and guide).
This three-fold nature of God can be better understood by comparing it to water, which also exists in three forms or states: solid (ice), liquid (also called water), and gas (steam or vapor). Each is still water, but each is manifested in a different form. The same holds true for God.
An alternate analogy is to consider an egg: there is the shell, the white, and the yolk. Each part is different, yet each is still an aspect of an egg. So it is with the three parts of God.
A lifelong student of the Bible, Peter DeHaan, PhD, wrote the 700-page website ABibleADay.com to encourage people to explore the Bible. His main blog and numerous books urge Christians to push past the status quo and reconsider how they practice their faith in every area of their lives.
