Wrath and Mercy
'Wrath' is righteous indignation and condemnation of God, the result of which is punishment. It's God's Djelal.
'Mercy' is compassion or forbearance shown to an offender or subject: clemency or kindness extended to someone instead of strictness or severity. It's God's Djemal.
THE MYSTERY OF WRATH AND MERCY
… With My punishment I visit whom I will; but My mercy extendeth to all things. (7/156) … So a wall will be put up betwixt them, with a gate therein. Within it will be Mercy throughout, and without it, all alongside, will be (Wrath and) Punishment! (57/13)
With My punishment I visit whom I will, this punishment is a light one; its aim is to give warning to the Self. This helps the individual to cleanse his soul. It is of a remedial character. This process begins in this world and may continue hereafter if the soul has not been thoroughly cleansed from the stain of his evil doings. My mercy extendeth to all things, God's most prominent characteristic is his infinite mercy and love of humanity; his forgiveness and compassion for the repentant and the penitent.
Without pain there is no pleasure. Without night there would be no day "Be sure we shall test you with something of fear and hunger, some loss in goods or lives or the fruits (of your toil), but give glad tidings to those who patiently persevere" (2/155)
