Do you believe Spirit baptism replaces water baptism?
No! But circumcision of the foreskin like that done to Abraham and his household has the same conotation in the Old Testament as water baptism is in the New Testament, that both phenomenons has no spiritual value except they now belong to the family of God.
The word "baptism" means to "wash"
or "wash away sins."
Spirit baptism happens when someone becomes save as in Titus 3:5,
I agree with this.
I believe we are first saved INITIALLY by God’s grace without works through faith.
When this happens… the Spirt baptizes us into one body and we are made to drink of one Spirit.
1 Corinthians 12:13
“For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.”
You said:…water baprism has no spiritual value…
Water baptism happens after we are initially saved by God’s grace, and after we have been baptized into the Spirit.
Water baptism is merely a part of our continued faith in God.
Just as Noah followed his instructions in building the Ark by faith (Hebrews 11:7).
We are to follow our instructions in the faith, too (Which would be the commands that come primarily from Jesus and His followers and not Moses).
Faith is spiritual. For without faith, it is impossible to please Him (God) (Hebrews 11:6).
After we are saved without works INITIALLY, we need to continue in the faith (Which leads us to both believe certain doctrines and to do certain things that God is calling us to do as a part of the New Testament).
Boasting is excluded when it comes to the faith (See: Romans 3:27).
So if we are following our instructions by faith like Noah did in building the Ark, we cannot boast because we are simply doing what God told us to do. Therefore the works spoken of in Ephesians 2:9 are not a part of the faith (Whereby men would boast in themselves).
You said:while water baprism has no spiritual value but to cleanse the dirt off of our skin (1 Peter 3:21).
To God Be The Glory
1 Peter 3:21 says,
“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:”
It says baptism saves us not [for] the putting away of the filth of the flesh but it saves us in having us to give an answer in that we have a good and clean conscience towards God (already). Our good and clean conscience was made possible when we first accepted Jesus as our Savior before we were water baptized. When we are first saved, we are born again spiritually by the power and resurrection of Jesus Christ with our past sins being cleansed and put away. We become a new creation in Christ. We are born again.
I believe that when Peter says, “baptism doth also now save us (not the putting away of the filth of the flesh,” I believe he is referring to how baptism does not put away of our sin nature entirely from us. While being born again spiritually does change us, we still need to crucify the affections and lusts by faith by fighting the good fight of faith in living out our faith whereby we may lay hold on eternal life (1 Timothy 6:12) (Galatians 5:24). For Paul says lets us cleanse ourselves from all filthiness of the flesh an spirit perfecting holiness in the fear of God (2 Corinthians 7:1). We are told to work out our salvation with fear and trembling (Philippians 2:12).
