Almighty, most holy,
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.

Lord God Almighty,
shaper and ruler of all creatures,
we pray for your great mercy,
that you guide us towards you,
for we cannot find our way.
And guide us to your will, to the need of our soul,
for we cannot do it ourselves. 
And make our mind steadfast in your will
and aware of our soul’s need.
Strengthen us against the temptations of the devil,
and remove from us all lust and every unrighteousness,
and shield us against our foes, seen and unseen.
Teach us to do your will,
that we may inwardly love you before all things with a pure mind.
For you are our maker and our redeemer,
our help, our comfort, our trust, our hope;
praise and glory be to you now and forever.

 Original translation: “that Thou guide us better than we have done, towards Thee, and guide us to Thy will, to the need of our soul, better than we can ourselves.”
Be our protection.
Direct our minds by your gracious presence.
Watch over our paths
and guide us with your love
through the hidden snares of life.
Fix our hearts on you as we go forward,
and following in faith,
arrive at your goal;
through Jesus Christ our Lord. Amen.

O Lord our God,
teach us to ask you for the right blessings.
Steer the vessel of our life toward yourself,
the tranquil haven of all storm-tossed souls.
Show us the course we should go.
Renew a willing spirit within us.
Let your Spirit curb our wayward senses
and guide and empower us to our true good,
to keep your laws,
and in all we do always rejoice in your glorious, joyful presence;
for yours is the glory and praise from all your saints forever and ever. Amen.

purity of lips,
a clean and innocent heart,
and rightness of action.
humility, patience, abstinence,
chastity, prudence, justice,
courage and self-control.
the Spirit of wisdom and understanding,
the Spirit of counsel and strength,
the Spirit of knowledge and godliness,
and of your fear.
Always lead me to seek your face
with all my heart, all my soul, all my mind.
Let me have a contrite and humble heart in your presence—
to prefer nothing to your love.
Most high, eternal, and ineffable Wisdom,
drive away from me the darkness of blindness and ignorance.
Most high and eternal Strength, rescue me.
Most high and eternal Courage, help me.
Most high and incomprehensible Light, illuminate me,
Most high and infinite Mercy, have mercy on me. [315.]

God guide me with your wisdom,
God discipline me with your justice,
God help me with your mercy,
God protect me with your strength.
God fill me with your fullness,
God shield me with your shade,
God fill me with your grace,
for the sake of your Anointed Son.
Jesu Christ, the Son of David,
visiting Boy in the Temple,
sacrificial Lamb in the Garden,
who died for me.
