Part 1: Who should be baptized?


Someone who believes the gospel of Jesus Christ, has placed their faith in Jesus as God’s Son, and in repentance of sin chooses to follow Jesus as their Lord, should be baptized.

1. The Gospel


Romans 3:23 “…for all have sinned and fall short of the glory of God….”
Romans 6:23 “For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.”
Romans 5:8 “but God shows his love for us in that while we were still sinners, Christ died for us.”
Romans 10:9 “because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.”

2. God's Son

The Bible reveals Jesus Christ to be the Son of the One True God.

Matthew 3:16-17 “And when Jesus was baptized, immediately he went up from the water, and behold, the heavens were opened to him, and he saw the Spirit of God descending like a dove and coming to rest on him; and behold, a voice from heaven said, ‘This is my beloved Son, with whom I am well pleased.’”

There is only one God who exists in three persons: God the Father, God the Son, and God the Holy Spirit. Jesus commanded us to be baptized in the name of the Father, and of the Son and of the Holy Spirit (Matthew 28:19).

God the Father made us, loves us, chose us to be his children, and sent his Son and Spirit to accomplish our salvation.

God the Son became a man, lived a sinless life, died in our place for our sins, and rose from the dead to save us.

God the Holy Spirit, sent by the Father and the Son, makes our dead hearts alive and dwells in every believer.

Do you believe in One God who exists in Three Persons--the Father, the Son, and the Holy Spirit?

3. Repentance

Acts 2:38 “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.”

The word “repent” means to make a 180º turn away from sin and towards God.

Are there any sins you do not repent of?

We must also repent of false gods and false religions. Giving ourselves fully to God and the Lord Jesus, we must no longer worship, pray to, honor, or participate with false gods. We should get rid of idols and other religious items.

2 Corinthians 6:14-16 “Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness? What accord has Christ with Belial? Or what portion does a believer share with an unbeliever? What agreement has the temple of God with idols? For we are the temple of the living God….”

Do you repent of false gods, false religions, and false religious activities?

4. Christ’s Lordship

Luke 9:23 “If anyone would come after me, let him deny himself and take up his cross daily and follow me.”

Romans 10:9 “because, if you confess with your mouth that Jesus is Lord ... you will be saved.”

Anyone who seeks to follow Jesus must follow him as Lord--meaning he is the boss of your life. We must be willing to deny ourselves (we are not the boss of our life) and obey Jesus in all he commands.

How do you answer the following questions?
  1. Do you believe you are a sinner and that you need Jesus?
  2. Do you believe that Jesus Christ is the Son of the One True God?
  3. Do you believe that Jesus died to pay for your sins to save you?
  4. Do you believe that Jesus rose from the dead?
  5. Are you ready to profess faith in Jesus as your Lord and Savior?
  6. Are you read to repent, be baptized, and start a new life with Jesus?

Part 2: What does baptism symbolize?

Romans 6:3-4, 6, 9-11 "Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life. ...We know that our old self was crucified with him in order that the body of sin might be brought to nothing, so that we would no longer be enslaved to sin. ... We know that Christ, being raised from the dead, will never die again; death no longer has dominion over him. For the death he died he died to sin, once for all, but the life he lives he lives to God. So you also must consider yourselves dead to sin and alive to God in Christ Jesus."
1. Baptism shows we died to sin with Christ. This has two applications: on the one hand, our old self which could never stop sinning has been killed and buried with Jesus. Now we have the freedom to stop constantly sinning. On the other hand, everyday we must consider ourselves dead to sin and continuously strive to kill what sinful thoughts and actions remains in us (Colossians 3:5).

2. Baptism shows we were raised to life with Christ. We are no longer dead and broken, but raised up, given new life, and completely recreated by God (2 Corinthians 5:17). We are to live to God--which means striving to honor, please, and obey God every moment of our life.



Acts 2:38 “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.”
3. Baptism shows our sins have been forgiven. Every sin we have every committed and every sin we will ever commit has been forgiven and erased by God. Isaiah 1:18 "Come now, let us reason together, says the Lord: though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall become like wool."

4. Baptism shows we have received the Holy Spirit. When we become a Christian God gives us an amazing gift: his Holy Spirit comes to live inside of us. God's Spirit brings our dead soul to life (John 6:63), helps us to know God's love (Romans 5:5), helps us to stop sinning (Philippians 2:13), and is a guarantee that we will inherit eternal life (Ephesians 1:14).

Galatians 3:26-29 "...for in Christ Jesus you are all sons of God, through faith. For as many of you as were baptized into Christ have put on Christ. There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus. And if you are Christ’s, then you are Abraham’s offspring, heirs according to promise. (Galatians 3:26-29)
5. Baptism shows that we are God's children. Baptism into Christ is like putting on Christ's ID badge and having full the access and privileges of a son in his father's house. You are a true child of God in Christ.

6. Baptism shows that we are members of God's family. Every Christian, regardless of social status and nationality, is a member of God's one, world-wide church family (1 Corinthians 12:13). We are his sons and daughters.

Those baptized are naturally added into the local expression of the church with whom they are baptized (Acts 2:41). Upon your baptism you become a member of Mustard Seed Christian Church. More information about local membership can be found in the appendix of this booklet.

Do you believe the MSCC statement of faith?

Part 3: Helpful information

Your baptism ceremony will consist of two parts. 

First you will be asked to make your public confession of faith. You will be asked:
“Do you believe that Jesus is the Christ, the Son of the living God?”
“Do you confess Jesus as your Lord and Savior?”

Second, you will get into the water. The one baptizing you will say, “I baptize you in the name of the Father and of the Son and of the Holy Spirit” and then you will be let under the water and pulled back up.

Practical tips:
  • The church will provide towels. You should bring a change of clothes.
  • The church has a robe you can wear for the baptism. You should bring a swimming suit or dark shirt and shorts to wear under the robe.
  • Plug your nose before being let under water.

Membership in Mustard Seed Christian Church is open to all persons of the Christian faith who are in agreement with the church’s statement of faith, mission, and values and who have been baptized into the Christian church with a local church that professes a faith consistent with historic, Biblical Christianity. Members also commit to regular attendance, using their gifts to the glory of God, and joyfully and sacrificially contributing offering out of their own compulsion.

Prospective members shall be examined by a pastor and admitted if they meet the criteria stated in this document. Members will then be added to the church directory that is viewable to all.

Membership may be forfeited or transferred at anytime by notifying a pastor of the reason for doing so.

Church membership may also be lost through excommunication if the member refuses to put reasonable effort towards repentance of any certain sin. The pastors must unanimously agree to excommunicate a church member and will only do so after multiple attempts to counsel the member to live according to God’s Word, the Bible. The pastors must not only instruct the member to put a stop to the sin in question but must also take steps to provide the church member with the adequate assistance and support needed to make effort towards overcoming the sin in question. (Matthew 18:15-20) 

The Statement of Faith of Mustard Seed Christian Church
We believe the scriptures, both Old and New Testaments, to be the inspired Word of God without error in the original writings, the complete revelation of his will for the salvation of men, and the Divine and final authority for all Christian faith and life. (2 Timothy 3:16)

We believe in one God, creator of all things, infinitely perfect, and eternally existing in three persons: Father, Son and Holy Spirit. (1 Peter 1:2)

We believe that Jesus Christ is true God and true man, having been conceived of the Holy Spirit and born of the Virgin Mary. He died on the cross a perfect and complete sacrifice for our sins according to the Scriptures. Further, he rose bodily from the dead, ascended into heaven, where he is at the right hand of the throne of God the Father Almighty. (Luke 1:34, 35; 1 Timothy 2:5; Hebrews 8:1,2)

We believe that the ministry of the Holy Spirit is to glorify the Lord Jesus Christ, and during this stage to convict men of sin, regenerate the sinner, indwell, guide, instruct, and empower the believer for godly living and service. (John 16:7-14)

We believe that man was created in the image of God but fell into sin and is therefore lost. We believe that the shed blood of Jesus Christ and His resurrection provide the only ground for justification and salvation for all who believe, and that only those who have faith in Jesus Christ are indwelled by the Holy Spirit and thus become the children of God. (Romans 3:21-26, 5:15–19, 8:15–17; Ephesians 2:8-9)

We believe in the personal return of the Lord Jesus Christ, and that this ‘blessed hope’ has a vital bearing on the personal life and service of the believer. (John 14:2, 3, 1 John 3:2,3)

We believe in the bodily resurrection of the dead: of the believer to everlasting blessedness and joy with their Lord, and the unbeliever to judgment and conscious punishment. (1 Thessalonians 4:13–18, Hebrews 9:27)

We believe that the true Church is composed of all such persons who have saving faith in Jesus Christ and have been regenerated by the Holy Spirit and are united in the body of Christ of which he is the head. (1 Corinthians 12:12,13)
