If you want to start an argument among people who Love Jesus and Believe in Him as the Son of God, all you have to do is bring up whether Baptism is necessary to be saved or not.
Then if you want to argue some more, mention that Immerision is the Biblical method of baptism.
I have heard many of the arguments that are for being Immersed into Christ for the remission of sin and the gift the Holy Spirit. I have also head many of the arguments that say that it is not necessary for salvation, all you have to do is believe and ask Jesus into your heart and you are saved, then you are immersed as a sign of being saved. I have heard many arguments that it doesn't matter if you are sprinkled, immersed, or have water poured upon you.
All I would like for anyone who argues for either side of the discussion is to study the Scripture and the context of what it says.
There is a chart that has some good wisdom within it, so take a look and see what it says.
The following by Ben Alexander will be of help in your understanding God's Plan of salvation.
What happens when you are immersed into Christ:
YOU.......Put on Christ Galatians 3:27
YOU.......Wash away your sins Acts 22:16
YOU........Have remission of your sins Acts 2:38
YOU........Are saved I Peter 3:21
YOU.........Are made free from sin Romans 6:1-
YOU.........Benefit by Jesus's death Romans 6:3-
YOU.........Enter the Body of Christ 1 Corinthians 12:13
Then what is your condition without being Immersed?
God's plan for saving mankind from sin. What must I do to be saved?
1. Hearing Romans 10:17
2. Faith in Jesus Christ Hebrews 11:6
3. Repentance of sin Acts 17:30
4. Confession of Christ Matthew 10:32
5. Burial with Christ by Immersion Romans 6:1-
Once I have received salavtion, then I must remain faithful until death in order not to give my salvation up.
II Peter 1:1-
