Fix Our Hearts with Steadfast Faith

Merciful and eternal God,
you did not spare your only Son
but gave him up for us all
that he might bear our sins on the cross.
Grant that our hearts may be so fixed
with steadfast faith in him
that we may not fear any trouble;
through your Son, Jesus Christ our Lord.
Amen.
