most high, and supreme God,
highest good, all good, wholly good,
you alone are good,
to you we render all praise, all glory,
all thanks, all honor, all blessing,
and we shall always ascribe all good to you.
Almighty, eternal, just, and merciful God,
help us wretches to do for you
what we know is your will
and always desire whatever is pleasing to you.
Purify us within, enlighten us within,
kindle us with the flame of your Holy Spirit,
so we may be able to follow in the footsteps of your Son,
our Lord Jesus Christ,
and by your grace alone
come to you, the Most High,
who in perfect Trinity and simple unity lives and reigns and glorifies God Almighty for ever and ever. Amen.
