Thomas Boston, Works, 2:596:
When the angels have wings to fly on God’s errands, yet they have also wings to cover their face and their feet, Isa. 6:2. There is no raising of pride in their hearts upon the doing of their duty, nor to keep them from any duty. But how does pride of heart keep us back from many duties as too low for us! and how often does it arise upon the doing any thing well; 2 Cor. 12:7. This is a heavy piece of the body of death, which the saints long to be rid of.
