Book Three, Chapter 51
That we Must Exercise Ourselves in Humble Works When we Cannot Attain to the Highest

You can not always continue in the more fervent desire of virtue, nor remain constantly in the higher degree of contemplation; but it must needs be that you sometimes, by reason of original corruption, descend to low things, and bear the burden of this corruptible life, even against your will and with weariness....On such occasions it is expedient for you to betake yourself to humble and exterior works, and recreate yourself in good actions; to await my coming and heavenly visitation with an assured hope...until you be again visited by Me and freed from all anxieties.  For I will cause you to forget your pains, and to enjoy internal quiet....And then will you say:  The sufferings of this time are not worthy to be compared with the future glory, which will be revealed in us.
