Spirit immersion occurs when we receive the Word and are transformed by it Rom 12:2 and we are baptised in the Holy Spirit 1Co 12:13 .   

This enables us to worship Him in Spirit And Truth Joh 4:23 .   

Water is physical and has NO spiritual properties.   

That which is flesh is flesh and that which is Spirit is Spirit Joh 3:6.   

Water baptism is just a symbol of what must happen in the Spirit for one to be Born Again and to enter the Kingdom Of Heaven Mat 3:11 .   

It is Spirit Baptism that produces a Son Of The Holy Spirit.   This is immersion into the Words Of Christ Joh 6:63 and into the Holy Spirit Of Christ Rom 8:11 .   

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 Holy Spirit Father, even so we also should walk in newness of life. Rom 6:4 The Sin Nature which we were born with is a result of Original Sin Gen 2:17 Gen 3:10,11.      It was crucified with Christ.      By Faith in Christ Jesus we are Born Again - made New Spirit beings Joh 3:5 Gal 5:25.      Your mind, emotions and body were not crucified with Christ.     You must crucify them by acts of your will.         ➛ let this mind be in you - Phi 2:5    ➛ mortify your members - Col 3:5    ➛ submit yourselves to the Lord - Jam 4:7    ➛ resist the devil - Jam 4:7    ➛ present your body - Rom 12:1    ➛ follow peace with all men - Heb 12:14    ➛ have faith in the Lord - Mar 11:22 and so on.      All the action verbs above indicate that our soul (mind, emotions and will) are not instantly perfected in the New Birth as our spirit is 1Co 2:6 Phi 3:15.      This verse says that we have Newness Of Life but we must walk in it.     `Walk` is an action verb implying that we have to knowingly and willfully decide to let the New Spirit being manifest.      Otherwise, it won`t.      Spirit Salvation is instantaneous.      Soul Salvation is a process totally dependent on our will while we are in the flesh.      At His return Jesus will finish His redemption work by translating us from corruptible to incorruptible 1Co 15:50-55.      In the meantime, our Lord expects us to press toward the mark Phi 3:14.      Immersion into Christ Jesus is the point of baptism.     It is not a one time event but a for-all-time state of absorption into His Holy Spirit so that He is in us and we are in Him.
