How do we know God can make us godly?

The transformation into a godly individual is solely the work of God, as highlighted in Psalm 12. When God saves a sinner, He grants them a new heart and nature, creating a profound change that enables them to love what God loves and detest what he detests. The process is described as God-likeness, where the believer’s radical transformation beyond mere moral improvement reflects divine grace. Thus, the assurance of becoming godly lies not in human effort but in the faithfulness of God to perform His work in those He saves.
