The mystic ladder of Divine love, according to Saint Bernard and Saint Thomas Step Four

The fourth step of this ladder of love is that whereby there is caused in the soul an habitual suffering because of the Beloved, yet without weariness. For, as Saint Augustine says, love makes all things that are great, grievous and burdensome to be almost naught. From this step the Bride was speaking when, desiring to attain to the last step, she said to the Spouse: ’set me as a seal upon thy heart, as a seal upon thine arm; for love—that is, the act and work of love—is strong as death, and emulation and importunity last as long as hell. The spirit here has so much strength that it has subjected the flesh and takes as little account of it as does the tree of one of its leaves. In no way does the soul here seek its own consolation or pleasure, either in God, or in aught else, nor does it desire or seek to pray to God for favours, for it sees clearly that it has already received enough of these, and all its anxiety is set upon the manner wherein it will be able to do something that is pleasing to God and to render Him some service such as He merits and in return for what it has received from Him, although it be greatly to its cost. The soul says in its heart and spirit: Ah, my God and Lord! How many are there that go to seek in Thee their own consolation and pleasure, and desire Thee to grant them favours and gifts; but those who long to do Thee pleasure and to give Thee something at their cost, setting their own interests last, are very few. The failure, my God, is not in Thy unwillingness to grant us new favours, but in our neglect to use those that we have received in Thy service alone, in order to constrain Thee to grant them to us continually. Exceeding lofty is this step of love; for, as the soul goes ever after God with love so true, imbued with the spirit of suffering for His sake, His Majesty oftentimes and quite habitually grants it joy, and visits it sweetly and delectably in the spirit; for the boundless love of Christ, the Word, cannot suffer the afflictions of His lover without succouring him. This He affirmed through Jeremias, saying: ‘I have remembered thee, pitying thy youth and tenderness, when thou wentest after Me in the wilderness. Speaking spiritually, this denotes the detachment which the soul now has interiorly from every creature, so that it rests not and nowhere finds quietness. This fourth step enkindles the soul and makes it to burn in such desire for God that it causes it to mount to the fifth, which is that which follows.
