We are made right with God through Christ and His blood (2 Corinthians 5:21).
Because of salvation, our spirits are righteous. This happens because God’s Spirit lives inside us (1 Corinthians 3:16).
This righteousness is the nature of God, given to us by the Holy Spirit (Romans 8:16).
To live this way every day, our imagination, thoughts, minds, emotions, will and bodies must obey/respond to guidance of the Holy Spirit (Galatians 5:16, 1 Thessalonians 5:23)
