Sure.
I learned in one theology class that whatever example we use with kids turns out to be wrong.
The water,steam, ice is wrong because each is its own reality and does not make one...this is modulism.
The triangle kind of works pretty well.
I used my own method.
Brought in a nice round big bread.
Then I cut it into three parts, but it was still one whole.
Then I made it into slices, spread some Nutella on it, and we had it as a snake with juice!
I think they might remember that better.
(no letters please. I'm sure this was wrong too!)
I have used the water analogy before, and I admit it is probably wrong in some respects.
I have another analogy.
Gods heart, His nature, His personality, His intentions, His outlooks, His choices, His essence, is expressed equally in Father, Son and Holy Spirit.
Father in heaven, on the throne,
Son, human, who came to earth, now in heaven with the Father
Holy Spirit, God who indwells us equally and is present everywhere.
They are perfectly God, yet equally three different identities and expressions
of this essence with different knowledge and emphasis.
All three are not the same, nor have the same knowledge etc.
Because they are eternal, they are God, but do they have to be identical
to be God in a true sense, or is our use of the word God the problem.
God the creator is His essence, who He is, yet He is expressed 3 different
ways, and as three separate identities. As far as we know, nothing else is
like this, so ofcourse we have problems expressing that which is beyond our
comprehension or description.
9 For in Christ all the fullness of the Deity lives in bodily form,
10 and you have been given fullness in Christ, who is the head over every power and authority
Col 2
The trinity in action
22 the Holy Spirit descended on him in bodily form like a dove. And a voice came from heaven: "You are my Son, whom I love; with you I am well pleased."
Luke 3
The Holy Spirit speaks to every child of God, at the same time, present in
their hearts, which appears that He alone can do this.
Though separate Jesus said this
30 I and the Father are one."
John 10
9 Anyone who has seen me has seen the Father
John 14
10 Don't you believe that I am in the Father, and that the Father is in me? The words I say to you are not just my own. Rather, it is the Father, living in me, who is doing his work.
John 14
