Collect (ECUSA):

Almighty God, you alone can bring into order the unruly wills and affections of sinners: Grant your people grace to love what you command and desire what you promise; that, among the swift and varied changes of the world, our hearts may surely there be fixed where true joys are to be found; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, now and for ever. Amen.

Almighty God,
you speak in our hearts when we do wrong, and make us sorry:
Help us to love to do your work; that,
whatever else changes, our love for you may be an unchanging source of joy;
through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, now and for ever. Amen.
