Poor in Spirit by Thomas Watson He that is poor in spirit is lowly in heart.
Rich men are commonly proud and scornful, but the poor are submissive.
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.
