What does it mean to be 'made willing in the day of God's power'?

'Made willing in the day of God's power' refers to the transformative work of the Holy Spirit in an individual’s life (Psalm 110:3). This act is the result of God's sovereign grace that allows sinners to respond positively to the gospel. Before this inner change, individuals are naturally inclined to reject God's call and remain in their state of spiritual death (Ephesians 2:1). However, when God intervenes, He provides both the desire and the ability to embrace faith in Christ. This promise affirms that salvation is not initiated by human effort but is a gracious act of God that brings about genuine faith and repentance within the heart of the believer.
