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!
