We worship the one true God, revealed in three persons—God the Father, God the Son, and God the Holy Spirit.
God is Triune
Reflections of the triune God are in His Creation. For example, time. The past, present and future are not the same, but you cannot have one without the others. God created man with a body, soul, and spirit—separable, but part of a unit (and made in the image of God).
Isaiah once saw a vision of the triune God. “In the year that King Uzziah died, I saw the LORD sitting on a throne” (Isaiah 6:1a). “Lord” here is Adonai, a name for God only.
“And one [seraph] cried to another and said: ‘Holy, holy, holy is the LORD of hosts; the whole earth is full of His glory!’” (Isaiah 6:3; word in brackets added) This is a different name, meaning Jehovah of hosts.
“Also I heard the voice of the LORD, saying: ‘Whom shall I send, and who will go for Us?’” (Isaiah 6:8a; emphasis added) Here is the Holy Trinity acting in concert.
God Magnifies the Son
“Who has ascended into heaven, or descended?….What is His name, and what is His Son’s name, if you know?” (Proverbs 30:4; emphasis added)
God the Father said, “‘Yet I have set My King on My holy hill of Zion.’ I will declare the decree: The LORD has said to Me, ‘You are My Son, today I have begotten You’” (Psalm 2:6-7; read whole chapter). God’s holy King is Christ. (Acts 4:24-26).
“For unto us a Child is born…And His name will be called Wonderful, Counselor, Mighty God, Everlasting Father, Prince of Peace” (Isaiah 9:6). “Mighty God” is from el gibor, which literally means God-man.
“Jesus said to them, ‘Most assuredly, I say to you, before Abraham was, I AM’” (John 8:58). I AM is the most holy name for God. (See Exodus 3:14.)
God is Holy
“Above it stood seraphim; each one had six wings: with two he covered his face, with two he covered his feet, and with two he flew. And one cried to another and said: ‘Holy, holy, holy is the LORD of hosts; the whole earth is full of His glory!’” (Isaiah 6:2-3)
The perfect character of God is His holiness. Holiness means that God will punish sin.
These seraphim are angels. They cover their eyes, because God is too holy for them to look upon. They cover their feet, because they are ashamed to stand before His presence. We think of God as some glorified grandfather or “The Man Upstairs.” But He is the thrice-holy God of Israel, and you have no concept of God until you see that!
When Isaiah saw God, he said, “Woe is me, for I am undone! Because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the LORD of hosts” (Isaiah 6:5). If you are not falling on your face before God, you have a serious problem.
“Then one of the seraphim flew to me, having in his hand a live coal which he had taken with the tongs from the altar. And he touched my mouth with it, and said: ‘Behold, this has touched your lips; your iniquity is taken away, and your sin purged’” (Isaiah 6:6-7).
Coal from an altar—where blood sacrifices were burned. This was a prophecy of Jesus’ blood, which cleanses us from all sin. (See Hebrews 9:22; 1 John 1:7.) If you do not see God as a God of love, grace, and forgiveness, you have missed the one true God.
