Charles H. Spurgeon on Psalms 109:17

Cursing is both good and bad. For we read in the Scriptures that holy men have often cursed. Indeed none can offer the Lord's Prayer rightly without cursing. For when he prays, "Hallowed be thy name, thy kingdom come, thy will be done", etc., he must include in the same outpouring of his desires all that is opposed to these, and say, cursed and execrated and dishonoured must all other names be, and all kingdoms which are opposed to thee must be destroyed and rent in pieces, and all devices and purposes formed against thee fall to the ground. —Martin Luther.
