“Which God?”
It is a fair question.
Human history is crowded with gods. Gods of nations and tribes. Gods of fertility and war. Philosophical gods. Deistic gods. Impersonal ultimate realities. Modern substitutes bearing names like Nature, Progress, Humanity, and the Universe.
So when a Christian says “God,” which God are we talking about?
We are talking about the God revealed in Jesus Christ.
The One who has left such an extraordinary evidential mark upon human history that we still reckon history around His entrance into it.
The One who calls His creatures to reason with Him.
The One whose revelation of an intelligible and orderly creation helped give rise to modern scientific inquiry.
The One whose commands to love God and neighbor have inspired many of the greatest humanitarian institutions in human civilization.
And most remarkably, the One who entered His own creation to save His creatures from within it.
There is none other like Him.
The God Who Entered History
Christianity does not begin with an abstract proposition that somewhere beyond the universe there might be some kind of deity.
It makes historical claims.
Jesus of Nazareth lived in first-century Judea. He taught publicly. He gathered disciples. He was crucified under Pontius Pilate. His followers proclaimed that He rose bodily from the dead, and they identified Him with the God revealed in the Hebrew Scriptures.
Whatever one ultimately concludes about those claims, Christianity planted its flag in history.
The Christian claim is therefore unusually exposed to investigation. Christianity asks us to consider what happened.
John’s Gospel opens with an astonishing identification:
“In the beginning was the Word, and the Word was with God, and the Word was God.”
John 1:1, ESV
Then comes the claim upon which Christianity stands:
“And the Word became flesh and dwelt among us.”
John 1:14, ESV
The eternal Logos entered His creation.
That changes the character of the question “Which God?”
Christians are identifying Someone.
The God Who Calls Us to Reason
Biblical faith does not require the abandonment of rational thought.
God tells Israel:
“Come now, let us reason together, says the LORD.”
Isaiah 1:18, ESV
Jesus repeatedly reasons from Scripture, evidence, ordinary experience, and logical consequence. Paul “reasoned” with people in synagogues and marketplaces (Acts 17:2, 17; 18:4). Christians are instructed to be prepared to give a reason for their hope (1 Peter 3:15).
This makes sense within the Christian conception of reality.
If reality originates in the rational agency of God, and human beings are created in His image, then our ability to investigate reality rationally is unsurprising.
The world is intelligible because its Creator is intelligent.
Logic is at home here.
So is evidence.
So is investigation.
The God Whose Creation Invited Scientific Investigation
Modern science did not arise from Christianity alone. Its development has a complex history involving Greek philosophy, medieval Islamic scholarship, technological development, mathematics, universities, patronage, and many individual cultures and thinkers.
Yet Christianity supplied important intellectual commitments within the civilization in which modern science emerged.
Nature was creation rather than deity.
Creation possessed order.
That order could be investigated.
Human beings possessed rational faculties capable of investigating it.
And because creation was contingent upon God’s will rather than logically necessary, investigators had to observe what God actually made.
This theological environment mattered.
Johannes Kepler described scientific investigation in explicitly theological terms. Robert Boyle regarded the study of nature as compatible with Christian devotion. Isaac Newton wrote extensively about God alongside his investigations of nature. The institutional history of universities and scientific societies likewise developed within a civilization deeply shaped by Christianity.
The theological proposition beneath this is older still:
“The heavens declare the glory of God, and the sky above proclaims his handiwork.”
Psalm 19:1, ESV
Creation was worth investigating because creation was meaningful.
The God Who Commands Love of Neighbor
Then there is Christianity’s humanitarian footprint.
Hospitals.
Schools and universities.
Orphan care.
Poor relief.
Missions combining evangelism with medicine and education.
Movements for prison reform and the abolition of slavery.
Organizations serving people whom their founders would never meet and from whom they expected nothing in return.
Christians have certainly failed their own standard throughout history. Sometimes catastrophically. Christianity makes no prediction that everyone bearing Christ’s name will consistently obey Him.
The relevant question is what the Christian ethic itself commands.
Jesus said:
“You shall love your neighbor as yourself.”
Matthew 22:39, ESV
Then He made “neighbor” painfully expansive.
The Good Samaritan crosses ethnic and religious boundaries to care for a wounded stranger who cannot repay him. Jesus commands love of enemies. He identifies care for the hungry, stranger, naked, sick, and imprisoned with service rendered to Him.
Christian humanitarianism therefore follows naturally from Christian anthropology.
Human beings possess value because they bear God’s image.
The vulnerable matter because human worth does not depend upon usefulness.
The stranger is my neighbor because moral obligation extends beyond my tribe.
The God Who Saves From Within His Creation
But here Christianity becomes truly distinctive.
God does not merely issue instructions from a safe metaphysical distance.
He enters the story.
The Creator takes on human nature.
He experiences hunger, exhaustion, rejection, grief, pain, and death.
The Christian gospel is that humanity’s rebellion against God cannot finally be repaired through education, technological progress, political organization, moral effort, or philosophical enlightenment. Reconciliation requires God Himself to act.
And He does.
“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.”
John 3:16, ESV
The cross therefore sits at the center of Christianity.
And beyond the cross stands the empty tomb.
Christianity’s answer to suffering and death is ultimately a Person who entered both and emerged victorious.
So, Which God?
The God revealed in Jesus Christ.
The God whose claim upon history is sufficiently concrete to be investigated.
The God who calls us to reason.
The God whose creation is orderly enough to investigate scientifically.
The God whose commands have sent generations outward to teach, heal, feed, shelter, liberate, and serve.
The God who did something still more extraordinary.
He entered His creation.
He walked among His creatures.
He suffered at their hands.
He died for sinners.
And Christians proclaim that He rose from the dead.
You can reject that claim.
You can investigate it.
You can challenge its evidence.
You can ask whether the Christian worldview actually accounts for the reality we inhabit.
Those are legitimate questions.
But “Which God?” has an answer.
Jesus Christ.
There is none other like Him.
