How do we know that we have been transformed by the Holy Spirit?

The transformation of a believer's heart is at the core of the Christian experience. This change is not merely behavioral; it is a profound renewal initiated by the Holy Spirit, marking the shift from the old nature dominated by sin to a new nature that craves holiness and godliness. As stated in Colossians 3, the 'old man' is put off, and the 'new man' is put on, revealing new desires that align with God's will. Believers will increasingly find sin distasteful and will strive for righteousness. This transformation is often gradual, as the Spirit continues to work within, increasing the believer's awareness of sin and prompting a pursuit of holiness.
