THE PURPOSE AND POWER
OF WATER BAPTISM
Teaching Notes
Purpose of the Teaching
To help believers understand the biblical meaning of water baptism, why Jesus commanded it, what it publicly declares, and how it marks a believer’s identification with the death, burial, and resurrection of Jesus Christ.
Key Scriptures
Matthew 28:18-20 - Jesus commands His disciples to make disciples and baptize them.
Acts 2:38-41 - Those who received the message were baptized.
Romans 6:3-4 - Baptism pictures our union with Christ in His death and resurrection.
Colossians 2:12 - We are buried with Christ in baptism and raised through faith.
Acts 8:26-39 - The Ethiopian official responds to the gospel by being baptized.
1 Peter 3:21 - Peter connects baptism with an appeal to God from a good conscience.
1. What Is Water Baptism?
Water baptism is an outward, public act of obedience that follows faith in Jesus Christ. The water itself does not save us; salvation is by grace through faith in Christ. Baptism is the God-given sign through which a believer publicly identifies with Jesus and declares a new life of discipleship.
Important Distinction
Baptism is not a substitute for repentance or faith. It is a response of faith and obedience. Ephesians 2:8-9 teaches that salvation is God’s gift, while baptism visibly expresses the believer’s response to the gospel.
2. The Purpose of Water Baptism
Obedience to Jesus: Jesus Himself commanded baptism as part of making disciples (Matthew 28:19-20).
Public identification with Christ: Baptism says openly: I belong to Jesus and I intend to follow Him.
A picture of the gospel: Going into the water pictures death and burial; rising from the water pictures resurrection and new life (Romans 6:3-4).
A declaration of a changed allegiance: The believer leaves the old life behind and now lives under the lordship of Jesus.
Connection to the community of believers: In Acts, baptism normally accompanied a person’s entrance into the visible community of disciples (Acts 2:41-42).
3. The Power of Water Baptism
The power of baptism is not magical power in the water. Its power is found in what God has accomplished through Jesus and in the believer’s faith-filled identification with that finished work.
It makes the gospel personal: The believer does not merely agree that Jesus died and rose; baptism dramatizes, ‘His death and resurrection now define my life.’
It marks a new beginning: Romans 6:4 connects baptism with walking in newness of life.
It creates a public line of testimony: Baptism gives the believer a memorable moment of declaring faith before others.
It strengthens discipleship: Obeying Jesus in baptism establishes a pattern: hear His Word, trust Him, and obey.
It points beyond the moment: Baptism is the beginning of a life of following Jesus, not the graduation ceremony of Christianity.
4. The Picture: Death, Burial, and Resurrection
Death - The old life under sin’s rule is no longer our identity.
Burial - The old life is left behind; we identify with Christ’s burial.
Resurrection - We rise to walk in a new life shaped by Jesus.
Read Romans 6:1-11 together and ask: What should be different in the life of someone who has been united with Christ?
5. Jesus and Baptism
Jesus was baptized by John (Matthew 3:13-17). His baptism was not repentance from personal sin; Jesus was sinless. It publicly identified Him with the Father’s will and the mission He came to fulfill. For His followers, baptism likewise becomes an act of surrender and obedience.
6. The Pattern in Acts
Acts 2:41 - People received the word and were baptized.
Acts 8:12 - Men and women believed the good news and were baptized.
Acts 8:36-38 - The Ethiopian official believed and immediately sought baptism.
Acts 10:44-48 - Cornelius’s household received the Holy Spirit and was commanded to be baptized.
Acts 16:30-34 - The Philippian jailer believed and was baptized with his household.
7. What Baptism Declares
Jesus Christ is my Lord.
My old life no longer defines me.
I have received the gospel and belong to Christ.
I intend to live as a disciple of Jesus.
I am not ashamed to identify publicly with Him.
8. Common Questions
Do I have to be perfect before being baptized?
No. Baptism is for believers who are trusting and following Jesus, not people who have achieved perfection.
Does baptism save me?
Scripture teaches salvation is by grace through faith. Baptism is the commanded response and public expression of that faith.
What if I was baptized before I personally understood or trusted Christ?
Many churches encourage a person to be baptized after personal faith so that the act genuinely expresses his or her own confession. Church traditions differ, so pastoral guidance can be helpful.
Why immersion?
Many churches practice immersion because the New Testament language and the death-burial-resurrection picture in Romans 6 are naturally represented by going under and rising from the water.
Personal Reflection
Have I personally trusted Jesus Christ and publicly identified with Him in baptism?
If I have been baptized, am I currently living out what my baptism declared?
Water baptism is not merely a church ceremony. It is a powerful public picture of the gospel and a believer’s decision to belong to Jesus. We go into the water identifying with His death and burial, and we rise declaring that because Jesus lives, we will walk in newness of life. The question after baptism is not simply, ‘Did I get wet?’ but, ‘Am I living the new life that I publicly declared?’
