Have you wondered what is God like? Or have you ever tried to teach kids about the Trinity? Many of us would use analogies to explain the Trinity. For example, I would say, "God is like an egg." An egg is made up of shell, white and yolk. God is like an egg in that He is 3-in-1 ... God the Father, the Son (Jesus Christ) and the Holy Spirit.
in that He is not made up of three parts ... one part (⅓) the Father, another part (⅓) Jesus Christ and a third part (⅓) the Holy Spirit. The Father is fully God; Jesus is fully God and the Holy Spirit is fully God. Each one is fully 100% God. Yet we do not have three gods but ONE God. The Trinity is not 1 + 1 + 1 but more like 1 x 1 x 1.
You can throw away one part of an egg (e.g., shell) and still have essentially an egg. But we cannot do that (assuming we can) with God. One cannot remove the Holy Spirit and still have the God as taught in the Bible.
What is H2O? If you say, "water" then you are incorrect. H2O is a combination of two particles (atoms) of hydrogen and one particle of oxygen and this compound can exist as water (liquid), ice (solid) and vapour (gas). Who is God? If you say, "Jesus Christ" then you MAY BE incorrect.
While the statement "God is Jesus Christ" is not always true, the inverse (Jesus Christ is God) is always true. Similarly, the Father is God and the Holy Spirit is God.
in that while water can change into vapour or ice, Jesus cannot change into the Father or the Holy Spirit.
Some people think that H2O cannot exist in all three states simultaneously but that is not true. There is what is called the 'triple point' ... the combination of pressure and temperature at which H2O can exist simultaneously in all three states: solid, liquid and gas. God is NOT like H2O in that He does not need the right pressure and temperature to exist as three persons. He is one God in three persons, all at the same time. The following verses attest to the Father, the Son and the Holy Spirit.
Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit (Matthew 28:19).
May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all (2 Corinthians 13:14).
The angel answered (Mary), “The Holy Spirit will come on you, and the power of the Most High (referring to the Father, italics mine) will overshadow you. So the holy one to be born will be called the Son of God.” (Luke 1:35)
One of my Sunday School students said, "How could Jesus (God) enter Mary's stomach (womb) and be born? She would explode!" Indeed, how can an infinite God be contained in a finite human womb! This is the Christmas paradox.
Do you know why I keep saying God is like an egg (or H2O) but God is not like an egg (or H2O)?
No analogy is adequate to explain God. He is much bigger and more complex than any illustration.
Postscript: Another illustration used to explain the Trinity is one man playing three different roles e.g., I am a son (to my parents), a husband (to my wife) and a father (to my sons). God is NOT one person playing three roles. There is only one God, and He exists as three Persons. In the above illustration, I in my role as the son would know what I know in my role as the father. “But concerning that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father only." (Matthew 24:36)
