One Lord, one faith, one baptism, Eph 4:5 It is simple and powerful    ➛ One Lord - Christ Jesus who is Creator, Mighty God and Saviour    ➛ One Faith - Salvation by Grace Through Faith In Christ Jesus    ➛ One Baptism - Immersed in the Words and Holy Spirit Of Christ Jesus

How can there be only One Baptism if there is Water Baptism and Spirit Baptism?   

For a person to become Born Again of the Holy Spirit they must receive Christ Jesus by Heart Faith as Saviour and Lord and confess His death and resurrection.   

That if you shall confess with your mouth the Lord Jesus, and shall believe in your heart that His Holy Spirit has raised Him from the dead, you shall be saved. Rom 10:9 This is the encapsulation of Grace, clearly pointing out our part which is faith in Jesus and confession of Him as risen Lord and Saviour.      The implication of our part being to believe on Jesus Christ and confess Him as risen Lord, is that He has done everything else!      It is why we call it amazing Grace!      It is why the gospel is nearly too good to be true!      Who raised Jesus from the dead?      He raised Himself Joh 10:17,18 by His Holy Spirit Rom 8:11

For with the heart man believes unto righteousness; and with the mouth confession is made unto salvation. Rom 10:10 It is Heart Faith that enables the miracle of the New Birth.      It is our personal confession of Jesus as Mighty God, Creator and loving Saviour that seals that miracle.
