Question
Who Is God in Christianity?
In Christianity, God is the one true God, the Creator of all things, eternal, holy, loving, and personal. He is not a force or an idea. He has revealed Himself in the Bible as Father, Son, and Holy Spirit — one God in three persons.

Intro
The God Christians confess
Christianity is not built on a vague religious feeling. It is built on a specific God who has spoken, acted, and made Himself known.
That God is:
one — there is no other
eternal — without beginning or end
the Creator of everything outside Himself
holy, righteous, and perfect
loving, faithful, and merciful
personal — He knows and can be known
revealed as Father, Son, and Holy Spirit
Christians worship this God, and only this God.
The God of Christianity is the God of the Bible from beginning to end. He is the God of Abraham, Isaac, and Jacob. He is the God who delivered Israel from Egypt, spoke through the prophets, and has now spoken finally through His Son Jesus Christ. Christians do not invent God, guess about Him, or reduce Him to what they hope He is like. They receive Him as He has revealed Himself in Scripture.
One God. This is the bedrock. Deuteronomy 6:4 says, “The Lord our God, the Lord is one.” Jesus repeats this in Mark 12:29 and calls it the first of all the commandments. Christianity is monotheistic. It does not allow for partners beside God or rivals to God. Whatever else Christians say about God, they never stop saying this.
Creator. God is not part of creation. He made it. Genesis 1:1 says, “In the beginning God created the heavens and the earth.” Every star, every cell, every moment of time exists because He spoke it into being. This means God is not dependent on the world for anything — the world is dependent on Him.
Holy. Holiness is not just moral purity. It is otherness. God is not a bigger version of us. He is different in kind. Isaiah 6 shows angels covering their faces and crying, “Holy, holy, holy, is the Lord of hosts.” Christians do not approach God casually. He is the source of all goodness, and sin is serious because He is holy.
Loving. God is not only holy — He is also love. 1 John 4:8 says plainly, “God is love.” His love is not sentimental. It is committed, covenantal, sacrificial. The cross is the clearest display of it: while we were still sinners, Christ died for us.
Personal. The God of Christianity is not a cosmic principle. He speaks, chooses, grieves, rejoices, forgives, and loves. He hears prayer. He answers. He is knowable because He has made Himself knowable.
Father, Son, and Holy Spirit. This is where Christianity is distinctive. The one God has revealed Himself as Father, Son, and Holy Spirit. Not three gods — one. Not three roles played by one person — three eternally distinct persons sharing one divine life. The Father sent the Son into the world. The Son lived, died, and rose for sinners. The Spirit now dwells in those who trust Him.
So when a Muslim asks, “Who is God in Christianity?” the answer is not a new god. It is the one true God — Creator, holy, loving, personal — who has fully made Himself known in Jesus Christ and who gives His Spirit to His people.
Muslims often assume Christians worship a different God — either three gods, or a God that is less than fully one. They want to know who the Christian God actually is, in plain terms, from the Bible.
Why Muslims Ask This
Christians worship the one true God who made everything, who is holy and loving, and who has fully revealed Himself as Father, Son, and Holy Spirit.
Christian View
Islam affirms one God, creator and sovereign, but views Him as strictly singular and distant in essence. Christianity affirms the same one God, but teaches He is eternally Father, Son, and Holy Spirit, and has drawn near personally in Christ.
Islamic View
Christians confess God on the basis of Scripture, not feeling.
Genesis 1:1 — God is the Creator of all things.
Deuteronomy 6:4 — the Lord is one.
Exodus 34:6–7 — God describes Himself as merciful, gracious, slow to anger, abounding in goodness and truth, and just.
Isaiah 6:3 — holy, holy, holy is the Lord.
Psalm 139 — God knows us completely.
1 John 4:8 — God is love.
John 4:24 — God is Spirit, and those who worship Him must worship in spirit and truth.
Matthew 28:19 — baptism in the name of the Father, the Son, and the Holy Spirit.
John 1:14, 18 — the Son has made the Father known.
Hebrews 1:1–3 — in these last days God has spoken to us by His Son.
Biblical Basis
“This sounds like a different God”
Christians believe it is the same true God who revealed Himself to Abraham, Moses, and the prophets — now revealed finally in Jesus. It is not a different God. It is the full picture of the same God.
“How can you say God is personal? God is above human categories”
Christians agree God is above us. That is why He had to come down to us. He is not a man, but He made us in His image so we could know Him. A God who cannot know and be known is not the God of the Bible.
“Isn’t Trinity a contradiction of monotheism?”
No. Christians hold both together: one God, three persons. This is not three gods, and it is not one person in three costumes. It is the one true God revealed as Father, Son, and Holy Spirit. See What Is the Trinity? for the full answer.
“Can we really know what God is like?”
Christians say we can, because God has told us. He has spoken in Scripture, and He has most clearly shown Himself in Jesus. Hebrews 1:3 calls Jesus the exact representation of God’s being. Guessing about God is unnecessary when He has made Himself clear.
Common Objection
The God Christians worship is not a projection, not a private preference, and not a tribal deity. He is the one true God, eternal, holy, loving, personal, and knowable.
He has spoken in the Scriptures. He has come to us in Jesus. He has sent His Spirit to dwell with His people. This is who God is in Christianity.
Conclusion
Why this matters
If you do not know who God is, you cannot know where you stand with Him. The first thing the Bible does is show us God, not ourselves.
Christianity teaches that God is not silent, not absent, and not unknowable. He has spoken. He has acted. He has revealed His character and His heart. That is where faith begins — not with guessing, but with receiving.
To know the true God is to find what every heart is looking for and cannot find in any substitute.
Why It Matters
Read What Is God Like in the Bible? next to go deeper into His attributes, then Is God Personal or Distant? to see how He relates to us.
Many assume the Christian God is either a second god beside Allah or a softer, less holy version of Him. He is neither. He is the one true God, revealed fully in Jesus Christ.
In Hebrew, YHWH is the covenant name of God, usually translated “Lord.” In Greek, the New Testament uses Theos for God and Kyrios for Lord — and applies both to Jesus.
