May God be pleased to give me His light, that I may speak profitably of this; for I have great need of it while treating of a night so dark and speak… - John of the Cross

If you do not learn to deny yourself, you can make no progress in perfection.

The soul then, thus disguised and clad in the vesture of hope, is secure from its second foe, the world, for St. Paul calls hope the helmet of salvation.10 Now a helmet is armor which protects and covers the whole head, and has no opening except in one place, where the eyes may look through. Hope is such a helmet, for it covers all the senses of the head of the soul in such a way that they cannot be lost in worldly things, and leaves no part of them exposed to the arrows of the world. It has one loophole only through which the eyes may look upwards only; this is the ordinary work of hope, to direct the eyes of the soul to God alone; as David says, “My eyes are always to our Lord,”11 looking for succor nowhere else; as he says in another psalm, “As the eyes of the handmaid on the hands of her mistress, so are our eyes to our Lord God until He have mercy on us,”12 hoping in Him. 9. The green vesture of hope — for the soul is then ever looking upwards unto God, disregarding all else, and delighting only in Him — is so pleasing to the Beloved that the soul obtains from Him all it hopes for. This is why He tells the soul in the Canticle, “Thou hast wounded My heart in one of thine eyes.”13 It would have been useless for the soul, if it had not put on the green robe of hope in God, to claim such love, for it would not have succeeded, because that which influences the Beloved, and prevails, is persevering hope. It is in the vesture of hope that the soul goes forth disguised in this secret and dark night; seeing that it goes forth so detached from all possession, without any consolations, that it regards nothing, and that its sole anxiety is about God, putting its “mouth in the dust if so be there may be hope” in the words of Jeremiah quoted already.14 10.

For the soul that is blind considers falsehood to be falsehood no longer, evil not to be evil, because it puts darkness for light, and light for darkness, and falls into endless disorders.
