If God created you and calls you to know Him, then one of the most important questions you can ask is:

Who is God?

Christianity doesn’t teach that God is simply a powerful force somewhere in the universe.

God is personal.

He knows. He speaks. He loves. He creates. He judges. He forgives.

And He invites us to know Him.

Jesus described eternal life this way:

“Now this is eternal life: that they know you, the only true God, and Jesus Christ, whom you have sent.”
— John 17:3

The Bible begins with God.

“In the beginning God created the heavens and the earth.”
— Genesis 1:1

Everything that exists ultimately depends upon Him.

The Psalms declare:

“The heavens declare the glory of God; the skies proclaim the work of his hands.”
— Psalm 19:1

The New Testament says that all things were created through Christ and for Christ (Colossians 1:16).

The universe is not God.

Nature is not God.

Human beings are not God.

God is the Creator, and everything else is creation.

That distinction matters.

If God created us, then our lives ultimately belong to Him.

God is not simply a bigger or better version of a human being.

He is holy.

When Isaiah received a vision of God, the heavenly beings called out:

“Holy, holy, holy is the LORD Almighty; the whole earth is full of his glory.”
— Isaiah 6:3

God is completely pure and righteous.

Peter therefore tells Christians:

“Be holy in all you do; for it is written: ‘Be holy, because I am holy.'”
— 1 Peter 1:15–16

God’s holiness helps us understand why sin matters.

We aren’t simply breaking arbitrary rules.

We are turning away from a holy God.

The Bible also tells us that God is perfectly just.

“He is the Rock, his works are perfect, and all his ways are just. A faithful God who does no wrong, upright and just is he.”
— Deuteronomy 32:4

God sees injustice.

He sees what happens in public and what happens in secret.

He doesn’t call evil good.

Psalm 89 says:

“Righteousness and justice are the foundation of your throne; love and faithfulness go before you.”
— Psalm 89:14

God’s justice means that evil matters.

But it also raises a difficult question:

What happens to people like us who have done wrong?

The answer eventually leads us back to Jesus.

The Bible gives us another essential truth:

“God is love.”
— 1 John 4:8

God’s holiness and justice don’t mean that He is cold or distant.

He loves His creation.

He loves people who have rejected Him.

He loves people who have run from Him.

Paul writes:

“But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.”
— Romans 5:8

The cross shows us what that love looks like.

God doesn’t ignore sin.

He makes a way for sinners to be reconciled to Him.

God has not left humanity without a witness.

Creation points toward Him (Psalm 19:1–4; Romans 1:19–20).

God has revealed Himself through Scripture:

“All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness.”
— 2 Timothy 3:16

And ultimately, God has revealed Himself through Jesus.

Hebrews says:

“In the past God spoke to our ancestors through the prophets… but in these last days he has spoken to us by his Son.”
— Hebrews 1:1–2

If you want to know what God is like, look at Jesus.

Christianity teaches that there is one God.

“Hear, O Israel: The LORD our God, the LORD is one.”
— Deuteronomy 6:4

Christians don’t worship many competing gods.

There is one God.

And yet Scripture also speaks of the Father, the Son, and the Holy Spirit as distinct persons who share the divine identity.

Jesus commanded His followers to baptize:

“In the name of the Father and of the Son and of the Holy Spirit.”
— Matthew 28:19

At Jesus’ baptism, the Son is present, the Spirit descends like a dove, and the Father’s voice speaks from heaven (Matthew 3:16–17).

The early church therefore came to describe God as Father, Son, and Holy Spirit—one God in three persons.

Christians call this the Trinity.

It is a mystery, but it is not meant to be a contradiction.

It is an attempt to faithfully describe what Scripture reveals about God.
