Baptism was not invented by Jesus in 30 A.D., it had been around for a very long time. Several places in Leviticus it describes how items that were used in Gods temple were ceremonially washed before they could be used inside. It wasnt because the items were dirty, but a symbolic action that showed certain items had been set aside for the Lords use. Many pagan religions began exercising similar ceremonies in which a new member to their cult would be completely immersed in water or even the blood of an animal. Anyone who refused to undergo such ceremonies was not allowed into the cult, indicating they did not believe. Similar reasoning spread throughout the Jews, if you were refusing to be baptized then it must be because you didnt believe, and thus, were not saved.
The first thing to understand about baptism is that it is not the forgiveness of sins. If baptism was the forgiveness of sins then Christ would not have needed to be baptized and there would not be so many scriptures that forget to mention baptism in regards to salvation (John 3:15, John 3:16, John 3:18, Acts 15:11, Acts 20:21, Ephesians 2:8-9, Romans 1:17, Romans 3:22, Romans 3:30, Romans 5:1-2, etc
). The idea that baptism is what saves a person is wrong, and the idea that infants go to hell if they arent baptized is ridiculous. Babies cant even form words, let alone understand the concepts of God, sin, forgiveness, etc
, so theres no reason to think a baby is responsible for making such decisions. Faith in Christ alone is the only thing required for salvation and the only thing capable of giving salvation. This isn't to say that baptism isnt important, just that it isnt the forgiveness of sins. Baptism is the response for someone who has believed and Jesus death, burial, and resurrection and has realized their sins have already been forgiven, because anyone who realizes this would want to set themselves aside for use by the Lord.
John 3:15 (NLT) so that everyone who believes in him will have eternal life.
John 3:16 (NLT) For God loved the world so much that he gave his one and only Son, so that everyone who believes in him will not perish but have eternal life.
John 3:18 (NLT) There is no judgment against anyone who believes in him. But anyone who does not believe in him has already been judged for not believing in Gods one and only Son.
Acts 15:11 (NLT) We believe that we are all saved the same way, by the undeserved grace of the Lord Jesus.
Acts 20:21 (NLT) I have had one message for Jews and Greeks alikethe necessity of repenting from sin and turning to God, and of having faith in our Lord Jesus.
Ephesians 2:8-9 (NLT) 8 God saved you by his grace when you believed. And you cant take credit for this; it is a gift from God. 9 Salvation is not a reward for the good things we have done, so none of us can boast about it.
Romans 1:17 (NLT) This Good News tells us how God makes us right in his sight. This is accomplished from start to finish by faith. As the Scriptures say, It is through faith that a righteous person has life.
Romans 3:22 (NLT) We are made right with God by placing our faith in Jesus Christ. And this is true for everyone who believes, no matter who we are.
Romans 3:30 (NLT) There is only one God, and he makes people right with himself only by faith, whether they are Jews or Gentiles.
Romans 5:1-2 (NLT) 1 Therefore, since we have been made right in Gods sight by faith, we have peace with God because of what Jesus Christ our Lord has done for us. 2 Because of our faith, Christ has brought us into this place of undeserved privilege where we now stand, and we confidently and joyfully look forward to sharing Gods glory.
Now, if we take a look at John 3:5 we can see that it cannot possibly mean that one must be baptized in order to be saved, if it was then it would be in direct contradiction with those verses I listed above and dozens more. When we take a look at the entire passage, John 3:1-21, no where is baptism even mentioned. To understand the true meaning of the passage you need to make sure we translate the passage into English correctly. The Hebrew word used in John 3:3 and John 3:7 is Strongs #509: (from ano 507; from above; by analogy, from the first; by implication, anew:--from above, again, from the beginning (very first), the top.). There is no English word that has all the same different means, so when translating you have to pick one. Several translations use from above but the majority seem to use again, though many have footnotes saying Or born from above (including NIV, NLT, and ESV).
With the use of the word again, instead of from above, it suggests to the reader that Jesus is referring to two births. This is false, water and spirit is referring to the same birth, so we can eliminate the idea that Jesus was saying you need to be born from womb, and then be born of the spirit. Plus, I think common sense tells that you would need to exist before you could be saved, so it is very unlikely that he was saying such a thing. From the text it is obvious that Nicodemus thought that Jesus meant he needed to be born again, because he was asking him how he could enter his mothers womb and be born a second time, so Jesus is more specific and says without being born of water and spirit instead. How do we know this isnt literal water? Look in verse 10 when Jesus says You are a teacher of Israel, but yet you dont understand these things? Baptism is not mentioned a single time in the Old Testament, so why would Jesus be expecting Nicodemus to think of baptism? He was most likely expecting for Nicodemus to recall versus such as Joel 2:28-29, Ezekiel 39:29, Isaiah 44:3, and Zechariah 12:10-13:1. The prophecies that describe the Spirit of God being poured out onto his people and cleanse them from sin. The water and spirit Jesus is referring to is the cleansing of the soul by the Holy Spirit, not baptism or being born from the womb.
Joel 2:28-29 (NLT) 28 Then, after doing all those things, I will pour out my Spirit upon all people. Your sons and daughters will prophesy. Your old men will dream dreams, and your young men will see visions. 29 In those days I will pour out my Spirit even on servantsmen and women alike.
Ezekiel 39:29 (NLT) And I will never again turn my face from them, for I will pour out my Spirit upon the people of Israel. I, the Sovereign Lord, have spoken!
Isaiah 44:3 (NLT) For I will pour out water to quench your thirst and to irrigate your parched fields. And I will pour out my Spirit on your descendants, and my blessing on your children.
Zechariah 12:10-13:1 (NLT) 10 Then I will pour out a spirit of grace and prayer on the family of David and on the people of Jerusalem. They will look on me whom they have pierced and mourn for him as for an only son. They will grieve bitterly for him as for a firstborn son who has died. 11 The sorrow and mourning in Jerusalem on that day will be like the great mourning for Hadad-rimmon in the valley of Megiddo. 12 All Israel will mourn, each clan by itself, and with the husbands separate from their wives. The clan of David will mourn alone, as will the clan of Nathan, 13 the clan of Levi, and the clan of Shimei. 14 Each of the surviving clans from Judah will mourn separately, and with the husbands separate from their wives. 1 On that day a fountain will be opened for the dynasty of David and for the people of Jerusalem, a fountain to cleanse them from all their sins and impurity.
Jeremiah 2:13 (NLT) For my people have done two evil things: They have abandoned me the fountain of living water. And they have dug for themselves cracked cisterns that can hold no water at all!
This is why people need to read their entire Bibles and stop reading single verses out of context.
