"He that is poor in spirit is lowly in heart. Rich men are commonly proud and scornful, but the poor are submissive. The poor in spirit roll themselves in the dust in the sense of their unworthiness. 'I abhor myself in dust' (Job 42:6). He that is poor in spirit looks at another's excellencies and his own infirmities. He denies not only his sins but his duties.
The more grace he has, the more humble he is, because he now sees himself a greater debtor to God. If he can do any duty, he acknowledges it is Christ's strength more than his own. As the ship gets to the haven more by the benefit of the wind than the sail, so when a Christian makes swift progress, it is more by wind of God's Spirit than the sail of his own endeavour. The poor in spirit, when he acts most like a saint, confesses himself to be 'the chief of sinners'. He blushes more at the defect of his graces than others do at the excess of their sins. He dares not say he has prayed or wept. He lives, yet not he, but Christ lives in him. He labours, yet not he, but the grace of God."
