Catechesis: Free Will

Conversion is such a change in the human mind, will, and heart effected by the activity of the Holy Spirit that the human being, through this activity of the Holy Spirit, can accept the grace offered. Indeed, all those who stubbornly persevere in resisting the Holy Spirit’s activities and movement, which take place through the Word, do not receive him but instead grieve the Holy Spirit and lose him.—FC SD II:83
