THE BAPTISM QUESTION
Water, Cleansing, and New Beginnings
When John the Baptist appeared in the wilderness baptizing people in the Jordan River, he did not introduce water into the biblical story for the first time.
Water had already been part of that story for centuries.
Throughout the Old Testament, God repeatedly used water in connection with life, cleansing, judgment, deliverance, and new beginnings. Understanding that background will help us understand why baptism appears so naturally when we reach the New Testament.
Before asking what Christian baptism means, let's go back and see what God had already been teaching His people.
What Was a Mikveh?
By the time John the Baptist appeared, ritual washing was already familiar in Jewish life.
A mikveh was a pool used for ritual purification. A person entered the water rather than simply having a little water placed upon the body. Jewish life included various ceremonial washings connected with purification and preparation before God.
The New Testament itself reflects this background. Mark mentions Jewish practices involving ceremonial washing, and Hebrews 9:10 refers to “various ceremonial washings.”
This helps us understand John's baptism.
When John began immersing people in water, the use of water itself did not appear out of nowhere. Israel already had a long history of washing, purification, and cleansing.
But John gave the people an urgent message:
“Repent, for the kingdom of heaven has come near.”
(Matthew 3:2)
The water was familiar.
John's call was new and urgent.
He was calling Israel to repentance and preparing the people for the coming Messiah.
Washing and Cleansing
Under the Law of Moses, washing was a familiar part of Israel's religious life.
Priests washed before serving. People washed after certain forms of ceremonial uncleanness. These washings did not mean that ordinary water could remove sin. They taught Israel something deeper:
God is holy, and those who approach Him need cleansing.
The prophets used the same language to speak about spiritual cleansing.
David prayed:
“Wash me, and I shall be whiter than snow.”
(Psalm 51:7)
Isaiah told Israel:
“Wash yourselves; make yourselves clean.”
(Isaiah 1:16)
The point was not cleaner bodies.
God wanted clean hearts.
By the time of the New Testament, ceremonial washing was familiar in Jewish life. Mark mentions the washing of hands, cups, pots, and other vessels, and Hebrews refers to the “various washings” associated with the old covenant.
Immersion itself was therefore not a strange idea when John appeared. The Jewish people already understood the connection between water, cleansing, and preparation before God.
But the biblical picture goes much deeper than ceremonial washing.
GOING DEEPER
Water Can Mean Life—and Judgment
Water appears at the very beginning of Scripture.
Genesis opens with the Spirit of God over the waters. Throughout Scripture, water is essential to physical life, and God sometimes uses that familiar reality to picture something greater.
Jeremiah calls God “the fountain of living waters” (Jeremiah 2:13).
Jesus later told the Samaritan woman that the water He gives becomes a spring leading to eternal life (John 4:14).
God is the source of life.
But water can also represent judgment.
The flood destroyed a corrupt world.
The Red Sea destroyed Pharaoh's army.
The same physical element can therefore appear in Scripture in very different settings.
Water can accompany life, cleansing, judgment, deliverance, and a new beginning.
Two Old Testament events are especially important because New Testament writers later connect them with baptism.
Noah: Grace, Faith, Judgment, and Deliverance
Genesis tells us:
“Noah found grace in the eyes of the LORD.”
(Genesis 6:8)
Notice where Noah's salvation began.
It began with God's grace.
Noah did not earn God's favor by building an ark. God graciously warned him about the coming judgment and told him what to do.
Hebrews later says:
“By faith Noah, being warned of God...prepared an ark.”
(Hebrews 11:7)
That is an important picture of biblical faith.
Noah believed God about something he had never seen, and because he believed God, he acted.
His obedience did not earn God's grace.
It was his response to God's grace.
Then the flood came.
The same waters that brought judgment upon the old world carried Noah and his family through that judgment into a new beginning.
Peter later draws attention to this very event:
“Eight souls were saved through water.”
(1 Peter 3:20)
Then he immediately connects Noah's experience with baptism in the following verse.
We will examine exactly what Peter means in a later study. For now, simply notice that Peter himself saw a connection between Noah's deliverance through water and Christian baptism.
Israel: From Slavery to Freedom
Generations later, Israel stood trapped between Pharaoh's army and the Red Sea.
They could not save themselves.
Moses told them:
“Fear not, stand firm, and see the salvation of the LORD.”
(Exodus 14:13)
God would provide the deliverance.
But then God told Moses:
“Tell the people of Israel to go forward.”
(Exodus 14:15)
Israel did not part the sea.
God did.
Israel did not defeat Pharaoh.
God did.
But when God opened the way, the people had to trust Him enough to walk through it.
On one side of the sea they were slaves pursued by Pharaoh.
On the other side they were a delivered people beginning a new life.
Paul later looked back at this event and wrote that Israel was:
“baptized into Moses in the cloud and in the sea.”
(1 Corinthians 10:2)
Again, we should be careful not to make the story say more than Paul says.
But Paul clearly saw Israel's passage through the sea as a useful picture for Christians.
There was an old life behind them.
There was deliverance by God.
And there was a new life ahead.
Naaman: Trusting God Enough to Obey
Another striking water story appears in 2 Kings 5.
Naaman was a powerful Syrian commander, but he had leprosy. Neither his position nor his wealth could cure him.
The prophet Elisha sent him a remarkably simple instruction:
“Go and wash in the Jordan seven times.”
(2 Kings 5:10)
Naaman was angry.
He expected something more impressive. He even complained that the rivers back home were better than the Jordan.
But that missed the point.
There was nothing magical about the Jordan River.
The power belonged to God.
Naaman simply had to decide whether he trusted God's word enough to do what God said.
When he finally did, he was healed.
Did dipping seven times earn his healing?
No.
Could Naaman boast that he had cured himself?
Of course not.
God healed him.
But Naaman received what God promised when he finally trusted God enough to obey Him.
That distinction will become important later when we ask whether baptism is a human “work” that earns salvation.
Stated a different way:
Was There Power in the Water?
When Elisha told Naaman to wash seven times in the Jordan, Naaman became angry. He expected something more impressive, and he thought the rivers of Damascus were better than the Jordan.
His servants asked a simple question: if the prophet had told him to do some great thing, wouldn't he have done it?
Naaman finally humbled himself and did what God had told him to do. After dipping seven times:
“His flesh was restored and became clean like that of a young boy.”
(2 Kings 5:14)
Was there healing power in the Jordan River?
No. The power was God's.
Naaman did not earn his healing by dipping seven times. God graciously provided the healing, and Naaman trusted God enough to accept His instructions.
That distinction is important:
Grace provided what Naaman could not provide for himself.
Faith accepted God's way.
God did the healing.
The issue was never whether water possessed power.
The issue was whether Naaman would trust God.
Ezekiel: Something Greater Was Coming
The prophets began looking beyond outward cleansing toward something much greater.
God promised through Ezekiel:
“I will sprinkle clean water on you, and you shall be clean.”
(Ezekiel 36:25)
But keep reading.
God also promised:
“I will give you a new heart, and a new spirit I will put within you.”
(Ezekiel 36:26)
The real promise was much greater than physical washing.
God was looking toward inner cleansing, a new heart, and a new life.
Stated another way:
Notice Who Does the Work
There is something easy to overlook in Ezekiel's promise.
Notice God's repeated words:
“I will sprinkle...”
“I will cleanse...”
“I will give...”
“I will put...”
God is the actor.
Israel had failed. The people could not cleanse their own hearts or create a new spirit within themselves.
God promised to do what they could not do.
That is important as we move toward the New Testament. Water, cleansing, a new heart, and the Spirit are not pictures of people earning their way back to God.
They are promises of what God would do for His people.
Salvation begins with God and His grace.
Physical Pictures Can Teach Spiritual Truths
Throughout Scripture, God often uses familiar physical things to teach deeper spiritual truths.
Bread can picture dependence upon God. Light can picture truth. A shepherd can picture God's care.
Water can picture life, cleansing, judgment, deliverance, and renewal.
That does not mean every mention of water in the Old Testament is secretly about baptism. We should never force a later meaning into an earlier passage.
But when the same themes appear repeatedly—cleansing, judgment, deliverance, new beginnings, and new life—they give us a biblical background for understanding the language the New Testament later uses.
The New Testament did not introduce these pictures out of nowhere.
It builds upon a story God had already been telling.
God Had Been Preparing the Picture
None of these Old Testament events by itself explains Christian baptism.
Noah was not practicing Christian baptism.
Israel crossing the Red Sea was not Christian baptism.
Naaman washing in the Jordan was not Christian baptism.
The ceremonial washings of Israel were not Christian baptism.
We should not turn illustrations into doctrines.
But taken together, they establish a biblical background that is difficult to miss.
For centuries God had used water in connection with:
cleansing,
judgment,
deliverance,
faith,
obedience,
and new beginnings.
So when John suddenly appeared in the wilderness saying:
“Repent, for the kingdom of heaven is at hand”
(Matthew 3:2)
and baptizing people in the Jordan, water itself was not the surprising part.
The important questions were:
Why was John baptizing?
What did his baptism mean?
And what was God preparing Israel for?
Those questions take us directly to our next study.
