We should only be baptized once we have been saved. (Repent / Accept Jesus as your Lord and Savior – Who Died on the Cross of Calvary for our Sin / Be reborn in the Holy Spirit and of Water)

Being baptized as a child is a religious event. A child has no sin. Jesus was an adult when he went to be baptized by John. Nowhere in the scripture / bible is there mention of: the baptism of children, (Except where there is mention of a entire “Household” being Baptized) this is a Catholic, Anglican, Lutheran, Presbyterian, practice / and not found in many other Denominations – https://en.wikipedia.org/wiki/Infant_baptism

Rather: Proverbs 22:6 – Train up a child in the way he should go: and when he is old, he will not depart from it

Question: Is there ever a justification for being “re-baptized”? I have questioned my baptism. I was very young and really did not comprehend the seriousness of what I was doing. I have considered being baptized again, but some say that it would not be right to be baptized a second time.

Answer: Your question is a very legitimate one. There are some people, even among religious leaders, who oppose any form of re-baptism.

For instance, in 1996, the General Conference of the United Methodist Church at a convention conducted in Denver, Colorado debated the matter of re-baptism. A position paper issued by the conference declared that Methodists who were baptized as infants should never be baptized again. The document explicitly stated:

“Whether a baptized infant grows up to be a professing Christian or not, that baptism stands valid.”

This position is flawed in many particulars, having no scriptural support whatsoever.

New Testament Precedent for Being Immersed a Second Time

While on his third missionary campaign, the apostle Paul came to the city of Ephesus. There, he encountered twelve men who formerly had been baptized with the type of baptism administered by John the Baptizer.

One might be inclined to conclude, therefore, that the apostle would have accepted these men as they were and merely organized them into a church.

But such was not the case. After questioning them as to the nature of their earlier baptism and determining that their pre-baptism instruction on the previous occasion had been lacking in essential details, Paul immersed these men into Christ (see Acts 19:1-5). A simple understanding of the text reveals that their first baptism was deficient in some way.

And here is an extremely important implication of this case of re-baptism. The case clearly demonstrates that in order for one’s baptism to be valid, accurate teaching and understanding must precede the rite. Otherwise, the act of baptism is a meaningless exercise and not based on faith (Rom. 10:17).

/ One must Repent and Born Again – “Jesus answered and said to him, ‘Most assuredly I say to you, unless one is born again, he cannot see the kingdom of God … Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.” John 3:3-15.

True Baptism — A One-time Act

Genuine baptism is needed only one time in a person’s life. Once a person has been baptized according to the full complement of scriptural instructions, he or she never has the need to repeat this new-birth process (cf. Jn. 3:3-5).

After a person has entered the family of Christ through baptism (1 Cor. 12:13; cf. Gal. 3:26-27), he is a part of the church, the household (family) of God (1 Tim. 3:15; cf. Eph. 2:19-22). The new Christian has access to all of the spiritual benefits of the in-Christ relationship (Eph. 1:3).

As a son or daughter of God within that sacred environment, the Christian prays to the heavenly Father for his or her personal needs by means of prayer (see Acts 8:22, 24; cf. Jas. 5:16) — including forgiveness for sins as we fail to live perfectly before God (cf. 1 Jn. 1:8; 2:1).

Qualifications for Baptism

Unfortunately, there are many in today’s world of Christendom that practice a form of what they call “baptism.”

When we compare what is practiced and taught by many with what the Bible teaches, we can see that a variety of doctrinal errors have developed that are not found in God’s word. Those corruptions invalidate a baptism and make it of none effect.

Therefore, many who have been administered what was called “baptism” but in fact is not need to be baptized again — this time with a more accurate understanding that precedes the event, just like the case in Acts 19:1-5.

Here are some situations in which re-baptism would be warranted.

Baptism without faith or understanding

If one was “baptized” as an infant, thus was lacking personal faith (Mk. 16:16; Acts 11:21), he should repudiate the meaningless earlier rite in which he had no decision-making power, even though his parents were sincere in subjecting him to the procedure.

In genuine faith, he should submit to the command in the proper way. Infants have neither the need nor the ability to respond to the gospel of Christ.

The same would be true for young children too young or immature to understand their accountability to the plan of salvation.

It is a tender thing to observe young children who want to please God. But many times, their desire precedes their understanding and accountability for personal sin.

If an adult concludes that they need to be re-baptized because they were baptized as an infant or as a sincere but immature child, we would encourage them to be immersed in faith and obedience. Thus, they can be assured of the forgiveness of their sins. Their decision will bring peace of mind and confidence by knowing they are obeying God from the heart with full understanding.

Baptism without immersion

If one was “baptized” in some fashion other than by immersion, then he needs to be baptized with the proper form. The word “baptism” literally translated means immersion, not sprinkling or pouring.

True baptism pictures the burial and resurrection of Jesus Christ. The sinner is buried in water and raised from this symbolic grave (cf. Rom. 6:3-4; Col. 2:12) just as the Lord was buried and then raised from the dead.

True baptism validates and proclaims one’s faith in the death and resurrection events. Being sprinkled with water or having water poured upon the head is no baptism at all. Such substitutes are without sanction in the New Testament. They are post-apostolic innovations.

Baptism without repentance

Baptism without true repentance is also ineffectual. I once heard about a man who emerged from the baptismal pool, turned to his wife, and said: “I hope you’re satisfied!”

No who is baptized without proper motive (and other prerequisites) can have validity in the divine scheme of things. Even John warned those who came to be baptized for a show without repentance. Only God’s wrath awaited those who were baptized with such false pretenses (Mt. 3:7).

Baptism without faith

If one is “baptized” without a sound faith, the ritual would be of no avail.

One might feel, for instance, that Jesus was a good man, perhaps even a “perfect man” — as the “Jehovah’s Witnesses” allege. As sincere as these may be, they deny that Christ is the Son of God (i.e., deity).

And yet, for various other reasons, they might desire to be baptized. But baptism grounded on false faith cannot be accounted as genuine.

Baptism without purpose

If one has yielded to baptism for some purpose other than that which is supplied by God’s word, he has not obeyed the Lord.

Baptism is never defined as “an outward sign of an inward grace.” It is not a mere representation of redemption for those who have already received forgiveness.

The purpose of baptism is “for the remission of sins” (Acts 2:38), to have sins “washed away” (Acts 22:16), to put the candidate “into Christ” (Rom. 6:3-4; Gal. 3:26-27), or into his “body” (1 Cor. 12:13). At this point, he is “saved” (Mk. 16:16; 1 Pet. 3:21).

The common resistance to the biblical proposition that baptism comes before salvation constitutes a bold rejection of the plain testimony of Scripture. One cannot be immersed “for the remission of sins” (Acts 2:38), if he believes his sins have been remitted already.

Your soul is too valuable, the plan is too simple and the remedy too easy to access to gamble — hoping that a former “baptism” will be alright in spite of the deficiencies associated therewith.

If you have any question about a previous baptism, I would encourage you to be safe and arrange for your baptism according to your informed knowledge.

Question: “I have sinned. Do I need to be baptized again?”

Answer: The question of whether a person who has sinned should be baptized again is a fairly common one. First, it is important that we understand what baptism is. Baptism does not save us or wash away our sins. Baptism is simply an illustration of what has occurred in a believer’s life when he/she believes in Jesus Christ.

Baptism illustrates a believer’s union with Christ in His death, burial, and resurrection. Romans 6:3-4 teaches us, “Or don’t you know that all of us who were baptized into Christ Jesus were baptized into his death? We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.”

The action of going under the water pictures being buried with Christ. The action of coming out of the water illustrates Christ’s resurrection and our identification with Him as we are raised to “walk in newness of life” (Romans 6:4 KJV).

Baptism is important because it is a step of obedience—a public declaration of faith in Christ and commitment to Him, and identification with Christ’s death, burial, and resurrection. If we know Jesus Christ as Savior and understand what baptism signifies when we are baptized, then we do not need to be baptized again.

If we did not know Jesus as Savior when we were baptized, then we do need to be baptized again. If we knew Jesus as Savior but did not truly understand what baptism signifies, then perhaps we do need to be rebaptized. But this is a matter of conscience between the believer and God.

It’s also important to understand that believers will continue to sin, although sin should have less and less of a hold on us as we mature in Christ, and the incidence of sinning should continue to lessen throughout our lives. When we do sin, we should confess it to God, asking Him to forgive us and to restore our intimate fellowship with Him. We have the promise that “he is faithful and just and will forgive us our sins and purify us from all unrighteousness” (1 John 1:9). Nowhere does the Bible say we must be rebaptized to be forgiven.
