I. SERMON NOTES​

​​

Introduction

​

Today (24 May) is a significant Sunday in the life of the Church. It is:

• Pentecost Sunday, celebrating the outpouring of the Holy Spirit in Acts 2.

• Aldersgate Sunday, remembering how John Wesley’s heart was “strangely warmed”.

• A day of Baptism, Confirmation of Faith, and Membership reception.

​

These themes come together in John 7:37–39, where Jesus declares:

“If anyone thirsts, let him come to me and drink.”

​

Jesus speaks these words during the Feast of Tabernacles (Sukkot), one of Israel’s major festivals. Historically, the feast remembered God’s provision for Israel in the wilderness, when the people lived in temporary shelters and God dwelt among them. Prophetically, it pointed forward to the coming Kingdom of God and the final gathering of His people.

A key feature of the festival was the water ceremony. Each day, priests drew water from the Pool of Siloam and poured it onto the altar while the people praised God. This remembered God bringing water from the rock in the wilderness and expressed hope that God would one day pour out His Spirit upon His people.

​

On the final and greatest day of the feast, as the priests completed the ceremony, Jesus stood and cried out:

​

“If anyone thirsts, let him come to me and drink.”

​

The “living water” Jesus spoke about is unpacked through three lenses.

​

1. The Living Water is a Gift that Inaugurates a New Reality

 

John explains in verse 39 that the living water refers to the Holy Spirit:

​

“Now this he said about the Spirit…”

​

The Spirit already existed before this moment. Scripture shows the Spirit active from creation and throughout the Old Testament. However, the Spirit had not yet been given in the fullness of the new covenant that would come after Jesus’ glorification — His death, resurrection, and ascension.

​

Pentecost in Acts 2 fulfilled this promise. After Jesus was exalted, the Holy Spirit was poured out upon believers. John 7:39 becomes the theological explanation of Acts 2.

​

The rivers had begun to flow.

​

Peter later declared in Acts 2:33 that Jesus, having been exalted at the right hand of God, “has poured out this that you yourselves are seeing and hearing.”

​

The Spirit is now poured out not on an altar, but on human hearts.

​

This is reflected in baptism. In Acts 2:38, Peter says:

​

“Repent and be baptised… and you will receive the gift of the Holy Spirit.”

​

Baptism and the Spirit are inseparable in the New Testament vision of entering into Christ.

​

Those entering church membership are not joining a club but being grafted into a Spirit-filled body. The same Spirit poured out at Pentecost is the life of the Church today. He makes worship more than performance, community more than friendship, and mission more than social work.

​

2. The Living Water is a Transformation that Flows In and Out of the Heart

 

Jesus says:

​

“Out of his heart will flow rivers of living water.”

​

There is debate over whether “his heart” refers to Christ or the believer. Some early church fathers understood it as Christ; many modern interpreters see it as the believer. The sermon holds both together:

​

The rivers flow from Christ through the believer.

​

Believers become bearers of Christ’s living water.

​

The Greek word translated “heart” here is not the usual word kardia, but koilia, meaning “hollow”, “belly”, or even “womb”. It refers to the deepest inner being — the source of spiritual vitality.

​

Jesus is describing a transformation that is not superficial but deeply internal. The Holy Spirit works in the innermost centre of a person’s life, and from that place rivers begin to flow outward.

​

Faith in Jesus is not a stagnant private experience. It produces overflowing rivers that bring life to others. Christians are not meant to be reservoirs hoarding grace, but rivers carrying God’s life to a thirsty world.

​

Paul echoes this in 1 Corinthians 12:13:

​

“For in one Spirit we were all baptised into one body…”

​

Individual rivers become part of a greater watershed.

​

John Wesley’s Aldersgate experience illustrates this transformation. Though deeply religious, he struggled spiritually until 24 May 1738, when during the reading of Luther’s preface to Romans, he felt his “heart strangely warmed”.

​

Wesley later wrote:

​

“I felt I did trust in Christ, Christ alone for salvation…”

​

What he knew intellectually became real within his heart. From that inner transformation, a river flowed out through his life, giving rise to Methodism, which continues to flow generations later.

​

Confident faith in Jesus produces believers whose lives overflow with joy, peace, generosity, and love that cannot be explained apart from the Spirit.

​

3. The Living Water is an Invitation Open to All Who Are Thirsty

 

Jesus declares:

​

“If anyone thirsts, let him come to me and drink.”

​

This echoes Isaiah 55:1:

​

“Come, everyone who thirsts, come to the waters.”

​

The invitation is universal. Jesus does not say “if the righteous thirst” or “if the educated thirst”. The qualification is simply thirst.

​

The invitation is not to ritual, religion, or a place, but to a Person: “come to me”.

​

Human restlessness ultimately points to a deeper thirst that only Christ can satisfy. Augustine expressed this well:

​

“Thou madest us for Thyself, and our heart is restless, until it repose in Thee.”

​

People thirst for meaning, forgiveness, peace, love, and assurance. Jesus alone can satisfy that thirst.

 

Confident faith begins by bringing our thirst to Him.

​

Conclusion

• The same Jesus who cried out in the Temple courts still calls today: “Come.”

• Pentecost, Aldersgate, baptism, and membership all point to the same reality: the fountain is open.

• Jesus invites all who are thirsty to come to Him, receive living water, and be renewed by the Holy Spirit.

• No one needs to leave thirsty.

• The fountain is open. Jesus is here. Come to Him.
