Many people through the ages have asked this question. Many have found the answer by reading the bible given to them, heard many preachers, teachers, and disciples of the Lord Jesus tell of him. So, I asked myself the question and how I would explain the God of Israel, the God that Christians also call Jesus. Here are my thoughts.
God is Elohim. Elohim, a Hebrew word that is plural. Throughout scripture we see the definition of Elohim taught as the Father, Son, and the Holy Ghost. In the Old Testament we do see the trichotomy mostly in symbolism involving the Son, and the Holy Spirit. The Father is direct in the Torah and the Tanach. The Son is spoken of, for instance, as the Captain of the Hosts and also as messiah types like Moses. The Holy Spirit is seen as water, wine, and oil in these scriptures. As we move along to the New Testament, which is a renewed covenant we see all three working through these writings being directly spoken of in context. God is made up of three persons, yet he is One. We are made in his image as body, soul, and spirit—three, yet one.
Genesis 1:1 KJV
In the beginning God created the heaven and the earth.
John 14:26 KJV
But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
God is Light. In the beginning of creation, God presents himself as light. He is the light of creation until he creates the sun to provide a light through the seasons. In the new earth to come God returns as the eternal light where his people dwell forever. We also see in his person that God is light, in which there is no darkness, meaning God is perfect, life is in himself, and in his being sin is not found. He is holy. With his light and knowledge he reveals the deep and hidden things, which he has written into his word, the bible for man to find. When we need strength, encouragement, wisdom and knowledge we can go to the scriptures and find light for the soul which quenches the thirst we have for our spiritual needs. Within him is light. He is made up of light, and light dwells within him. He is bright, and so bright that no man can physically look upon him and live. This he tells Elijah so that he can go into the creft of the rock and God can show his back to him because God’s glory—his light, the shekinah would strike him dead. Why? Because we do not live in glorified bodies. Our bodies are corrupted by sin that came through the sin of Adam and Eve.
1 John 1:5 KJV
This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.
Daniel 2:22 KJV
He revealeth the deep and secret things: he knoweth what is in the darkness, and the light dwelleth with him.
God is Light and Salvation. When I need light I go to Jesus to ask for strength and his light to light my paths so that I may stay and live in righteousness, for God is my strength that I need daily to ward off evil. He is life, and life on earth depends upon light to continue, and we must need light to continue living within our spirit man, the spirit that God breathed into us. When we are living righteously, we have his light and his light is sensed by all in the world, both those who live for Jesus, and by those who don’t. When we read his word, listen for his voice to guide us, with these paths we see his light and his goodness and love.
Psalm 27:1 KJV
The Lord is my light and my salvation; whom shall I fear? the Lordis the strength of my life; of whom shall I be afraid?
Psalm 36:9 KJV
For with thee is the fountain of life: in thy light shall we see light.
This is how I would describe God to anyone in the world. There is only one path to eternal life, and that is through Jesus the Son of God, the logos—the Word.
John 1:1 KJV
In the beginning was the Word, and the Word was with God, and the Word was God.
