Catechesis: Free Will

For we should not and cannot always judge from feeling about the presence, work, and gifts of the Holy Spirit, as to how and when they are experienced in the heart. They are often covered and happen in great weakness. Therefore, we should be certain about and agree with the promise that God’s Word preached and heard is truly an office and work of the Holy Spirit. He is certainly effective and works in our hearts by them.—FC SD II:56
