Your new birth is through the Word and the Spirit. The word of the gospel is about the Word who became flesh, Jesus Christ our Lord (John 1:14). New birth is through faith in Christ who died for our sins, our Lord Jesus risen from the dead (1 Corinthians 15:1-4). The Holy Spirit, who inspired the written word of God, brings your new birth through the gospel of Christ.
Your new birth means you are transformed, cleansed, and renewed (Romans 12:2; Ephesians 2:4; 1 John 1:7). Your mind, will and emotions are transformed and renewed. You are cleansed of all sin. It is by the Holy Spirit who regenerates you, that you become a new creation in Christ (2 Corinthians 5:17).
Before new birth, you were spiritually dead, but now made alive in Christ Jesus by the power of the Holy Spirit. You witness an actual miracle of God in your life. It is the power of God unto salvation, through the gospel of our Lord Jesus Christ (Romans 1:16; 10:9).
The same Spirit of God who moved in creation, now moves in your new birth. When you are truly born again, that is regeneration. If anyone is in Christ, he has become a new creation (2 Corinthians 5:17). The Holy Spirit regenerates your heart, which is the mind, will and emotions (Romans 12:2). The gospel comes to you not in word only, but in power and much assurance through the Holy Spirit (1 Thessalonians. 1:5).
