And these be the common Cheer which He sheweth to us in this life; therewith mingling the third: and that is His Blissful Cheer, like, in part, as it shall be in Heaven. And that by gracious touching and sweet lighting of the spiritual life, whereby that we are kept in sure faith, hope, and charity, with contrition and devotion, and also with contemplation and all manner of true solace and sweet comforts.”
