The Great Litany is especially appropriate to pray during Lent, as the rubrics confirm.  

The Anglican Service Book describes The Great Litany like this:

Litanies as forms of prayer are very old, dating from before the fourth century, and for a long time constituted a major part of the congregation's participation in the Mass.  The Great Litany in the Book of Common Prayer derives from the first English litany, compiled by Thomas Cranmer in 1544, drawing from the Sarum rite, the Liturgy of Saint John Chrysostom, and a Latin litany composed by Martin Luther.  The three invocations of saints that appeared in this litany were deleted before it was included in the 1549 Prayer Book.  For much of the history of the Anglican Church, the use of the Great Litany after Morning Prayer on Sundays, Wednesdays, and Friday has been required.

I wonder how many of you plan to pray this prayer as a part of your Lenten disciplines?  Here it is for your viewing pleasure:

To be said or sung, kneeling, standing, or in procession; before the 
Eucharist or after the Collects of Morning or Evening Prayer; or 
separately; especially in Lent and on Rogation days. 

O God the Father, Creator of heaven and earth,
Have mercy upon us. 

O God the Son, Redeemer of the world,
Have mercy upon us. 

O God the Holy Spirit, Sanctifier of the faithful,
Have mercy upon us. 

O holy, blessed, and glorious Trinity, one God,
Have mercy upon us. 

Remember not, Lord Christ, our offenses, nor the offenses
of our forefathers; neither reward us according to our sins.
Spare us, good Lord, spare thy people, whom thou hast
redeemed with thy most precious blood, and by thy mercy
preserve us, for ever.

When the Litany is sung or said immediately before the Eucharist, the 
Litany concludes here, and the Eucharist begins with the Salutation and 
the Collect of the Day.<o:p></o:p>

On all other occasions, the Officiant and People say together<o:p></o:p>

Our Father, who art in heaven,
    hallowed be thy Name,
    thy kingdom come,
    thy will be done,
        on earth as it is in heaven. 
Give us this day our daily bread.
And forgive us our trespasses,
    as we forgive those who trespass against us. 
And lead us not into temptation,
    but deliver us from evil. Amen. 

V.     O Lord, let thy mercy be showed upon us; 
R.     As we do put our trust in thee. 

The Officiant concludes with the following or some other Collect<o:p></o:p>

Let us pray.<o:p></o:p>

Almighty God, who hast promised to hear the petitions of
those who ask in thy Son's Name: We beseech thee mercifully
to incline thine ear to us who have now made our prayers
and supplications unto thee; and grant that those things
which we have asked faithfully according to thy will, may be
obtained effectually, to the relief of our necessity, and to the
setting forth of thy glory; through Jesus Christ our Lord. 
Amen.<o:p></o:p>

The Officiant may add other Prayers, and end the Litany, saying 

The grace of our Lord Jesus Christ, and the love of God, and the 
fellowship of the Holy Ghost, be with us all evermore.
Amen.<o:p></o:p>

The Supplication<o:p></o:p>

For use in the Litany in place of the Versicle and Collect which follows 
the Lord's Prayer; or at the end or Morning or Evening Prayer; or as a 
separate devotion; especially in times of war, or of national anxiety, or of 
disaster.<o:p></o:p>

O Lord, arise, help us;
And deliver us for thy Name's sake.<o:p></o:p>

         Christ. 

The Officiant concludes<o:p></o:p>

Let us pray.<o:p></o:p>

We humbly beseech thee, O Father, mercifully to look upon
our infirmities; and, for the glory of your Name, turn from us
all those evils that we most justly have deserved; and grant
that in all our troubles we may put our whole trust and
confidence in thy mercy, and evermore serve thee in holiness
and pureness of living, to thy honor and glory; through our
only Mediator and Advocate, Jesus Christ our Lord. Amen.<o:p></o:p>
