try looking at it like this....I must acknowledge that the following object lesson is only an attempt to comprehend the Trinity. Any explanation of the Trinity falls short of the magnificent reality of God being three unique Persons, and at the same time One Person! Ultimately, it requires faith to accept what God says in his Word to be true.
Props: water, ice, jar with water in it and covered in plastic, and/or a cup of hot water. Allow the water in the jar to set for a few hours in the heat so that water droplets form on the inside of the plastic top.
God In Three Persons:
The Bible teaches us that God is three unique persons, yet he is ONE GOD. He is God the FATHER, God the SON (JESUS), and God the HOLY SPIRIT. We call this the Trinity*, or triune nature of God*. This is hard to understand, even for adults. However, water is a great example of how something can be three different things, and at the same time remain one thing. Water can be a liquid, a solid (ice), and a gas (vapor/steam).
Show the different props as you name the different states of water. When you get to gas, show the jar with water droplets and explain that the water is vaporizing or becoming a gas. You cannot see the process of water turning into a gas, only the effects of the gas after it rises to the top and lands on the plastic. You can also use a hot cup of hot water and allow the children to feel the warm steam rising to touch their hands.
Even though there are three uniquely different states of water, (liquid, solid, and gas) they are still water. In the same way, these states of water can remind us of the triune nature of God.
The solid form of water (ice) reminds us of God the FATHER. Ice is hard. It is solid. In the same way, God the FATHER is our solid foundation. ("Righteousness and justice are the foundation of your throne; love and faithfulness go before you." Psalm 89:14)
The liquid form of water reminds us of God the SON. Water is useful for cleansing. In the same way, God the SON, died on the cross to cleanse us of our sin. ("How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!" Hebrews 9:14)
The gas form of water reminds us of God the HOLY SPIRIT. Gas cannot be seen, but you can see the effects of it. As we did when we saw the water droplets on the plastic, or felt the warmth of the steam from the hot water. In the same way, the HOLY SPIRIT cannot be seen, but the effects of his presence can be seen and felt in our lives as the HOLY SPIRIT works to make his will known to us and to change us to be more like him. ("I have much more to say to you, more than you can now bear. But when he, the Spirit of truth, comes, he will guide you into all truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come. He will bring glory to me by taking from what is mine and making it known to you. All that belongs to the Father is mine. That is why I said the Spirit will take from what is mine and make it known to you. John 16:12-15 )
The next time you drink a glass of water, or eat an ice cube, or feel the effects of steam, let this lesson on water remind you that God is three Persons in One!
* The Bible never mentions the word, trinity, or triune nature of God. However, there are plenty of references to the trinity. Here are just a few:
Genesis 1:26 Then God said, "Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground."
John 1:1-2, 14 In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made...The Word became flesh and made his dwelling among us.
Matthew 1:23 "The virgin will be with child and will give birth to a son, and they will call him Immanuel" --which means, "God with us."
John 14:9,11 "...Anyone who has seen me (Jesus) has seen the Father...Believe me when I say that I am in the Father and the Father is in me..."
John 14:25-26 "All this I have spoken while still with you. But the Counselor, the Holy Spirit, whom the Father will send in my name will teach you all things and will remind you of everything I have said to you."
Ephesians 1:13-14 "And you also were included in Christ when you heard the word of truth, the gospel of your salvation. Having believed, you were marked in him with a seal, the promised Holy Spirit, who is a deposit guaranteeing our inheritance until the redemption of those who are God's possession--to the praise of his glory.
Colossians 1:15-20 "He is the image of the invisible God, the firstborn over all creation. For by him all things were created
