D. Martyn Lloyd-Jones, referring to Matthew 5:7, writes:
This Beatitude follows all the others; therefore I put it in this form. I am poor in spirit; I realize that I have no righteousness; I realize that face-to-face with God and His righteousness I am utterly helpless; I can do nothing. Not only that. I mourn because of the sin that is within me; I have come to see, as a result of the operation of the Holy Spirit, the blackness of my own heart. I know what it is to cry out, ‘O wretched man that I am! Who shall deliver me?’ and desire to be rid of this vileness that is within me. Not only that. I am meek, which means that now that I have experienced this true view of myself, nobody else can hurt me, nobody else can insult me, nobody can ever say anything too bad about me. I have seen myself, and my greatest enemy does not know the worst about me. I have seen myself as something truly hateful, and it is because of this that I have hungered and thirsted after righteousness. I have longed for it. I have seen that I cannot create or produce it, and that nobody else can. I have seen my desperate position in the sight of God. I have hungered and thirsted for that righteousness which will put me right with God, that will reconcile me to God, and give me a new nature and life. And I have seen it in Christ. I have been filled; I have received it all as a free gift.
Does it not follow inevitably that, if I have seen and experienced all that, my attitude towards everybody else must be completely and entirely changed? If all that is true of me, I no longer see men as I used to see them. I see them now with a Christian eye. I see them as the dupes and the victims and the slaves of sin and Satan and of the way of the world. I have come to see them not simply as men whom I dislike but as men to be pitied. I have come to see them as being governed by the god of this world, as being still where once I was, and would be yet but for the grace of God. So I am sorry for them. I do not merely see them and what they do. I see them as the slaves of hell and of Satan, and my whole attitude toward them is changed. And because of that, of course, I can be and must be merciful with respect to them. I differentiate between the sinner and his sin. I see everybody who is in a state of sin as one who is to be pitied.
