What does true conversion look like according to the Bible?

Ryle emphasizes that mere outward reform is insufficient for true conversion. In Luke 11:24-26, Jesus warns against being satisfied with the removal of evil without a corresponding inward transformation. A heart that is not filled with the Holy Spirit remains vulnerable to worse evils reentering. True conversion includes a radical change of heart and mind, where the believer is not only cleansed from past sins but also indwelled by the Spirit of God. This vital relationship with Christ is what leads to genuine spiritual growth, resulting in a life marked by holiness and obedience.
