Quoth Bl. John Henry Newman:

May He support us all the day long, till the shades lengthen, and the evening comes, and the busy world is hushed, and the fever of life is over, and our work is done! Then in His mercy may He give us safe lodging, and a holy rest, and peace at the last.

— from Sermon #20, Wisdom and Innocence, preached 19 February 1843 at Littlemore

As it so happens, Arvo Pärt has set this to music, in his 2000 composition "Littlemore Tractus":

From "Christian Discourses", Søren Kierkegaard

Father in Heaven, well we know that it is Thou
that givest both to will and to do, that also longing,
when it leads us to renew the fellowship with our Savior and Redeemer,
is from Thee. Father in Heaven, longing is Thy gift.

But when longing lays hold of us, oh, that we might lay hold of the longing;
when it would carry us away, that we might give ourselves up.
When Thou art near to summon us,
that we also might keep near to Thee in supplication.
When Thou in the longing dost offer us the highest good,
oh, that we might hold it fast!

O Infinite Love

Thou loving Father, everything goes wrong for me and yet Thou art love.

I have even failed in holding fast to this—that Thou art love, and yet Thou art love.

Wherever I turn, the only thing that I cannot do without is that Thou art love, and that is why, even when I have not held fast to the faith that Thou art love, I believe that Thou dost permit through love that it should be so, O Infinite Love.

from The Prayers of Kierkegaard

Santa Teresa de Ávila nos dice:

Nada te turbe;
nada te espante;
todo se pasa;
Dios no se muda,
la paciencia
todo lo alcanza.
Quien a Dios tiene,
nada le falta.
Solo Dios basta.

A Prayer by Thomas Merton

My Lord God, I have no idea where I am going. I do not see the road ahead of me. I cannot know for certain where it will end. Nor do I really know myself, and the fact that I think I am following your will does not mean that I am actually doing so. But I believe that the desire to please you does in fact please you. And I hope I have that desire in all that I am doing. I hope that I will never do anything apart from that desire. And I know that if I do this you will lead me by the right road, though I may know nothing about it. Therefore I will trust you always though I may seem to be lost and in the shadow of death. I will not fear, for you are ever with me, and you will never leave me to face my perils alone.

from Thoughts in Solitude

[Attributed to St. Francis]

Lord, make me an instrument of Your peace.
Where there is hatred, let me sow love;
where there is injury, pardon;
where there is doubt, faith;
where there is despair, hope;
where there is darkness, light;
and where there is sadness, joy.
O Divine Master,
grant that I may not so much seek
to be consoled as to console;
to be understood as to understand;
to be loved as to love;
for it is in giving that we receive;
it is in pardoning that we are pardoned;
and it is in dying that we are born to eternal life.
