Many today are content knowing that they were sprinkled when they were children in the church. Yet, in the New Testament, all who were baptized were required to believe in Jesus Christ with all of their hearts (Acts 8:36) and then they were taken and baptized in water (Acts 8:38). Nothing has changed. If you have not been baptized since you have become a believer, you should have it done.
Many are unclear about baptism. For instance, there is not just one baptism spoken of in scripture, but three. There is the baptism that saves us by the baptism of blood. There is the baptism of water and there is the baptism of the Holy Spirit.
The baptism of salvation is not recognized by most churchs as actual baptism. But that does not mean it is not baptism. There is only one baptism that saves a man and it is the baptism of blood. The scripture below explains that the water baptism is the figure of the baptism that saves us. When we get baptized in water, we do nothing that pertains to the putting away of the flesh, but it gives us a good conscience towards God.
1 Peter 3:21 The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:
In these verses, it talks about being baptized into Christ, not being baptized in the name of Chirst. We are baptized into Christ when we are born again. This is the first baptism. If one does not recieve this baptism, one cannot recieve the baptism of the Holy Spirit because the temple must be sanctified by blood and made Holy before God will put his Spirit into it.
Romans 6:3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
5 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
6 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
7 For he that is dead is freed from sin.
8 Now if we be dead with Christ, we believe that we shall also live with him:
9 Knowing that Christ being raised from the dead dieth no more; death hath no more dominion over him.
10 For in that he died, he died unto sin once: but in that he liveth, he liveth unto God.
11 Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
1 Corinthians 12:13 For in one Spirit we were all baptized into one body, whether Jews or Greeks, whether bond or free; and were all given to drink into one Spirit.
Ephesians 4:5 one Lord, one faith, one baptism,
