From Alec Motyer's book Isaiah by the Day. Motyer is commenting on the pride of Moab, detailed in Chapter 15-16:
Faith and pride cannot co-habit, and pride puts on many guises. There is denominational pride which says we have the right way to run a church; our doctrines are the essence of orthodoxy. Beware of it, for nothing will close a church faster. There is domestic pride - look at our children how they are walking with God, unlike some we could mention! And then there is the dreaded personal pride, the 'I can cope' syndrome: 'I've got to work through this for myself'; 'I can handle it'. Pride is the ultimate expression of salvation by works; it is practical atheism. It shows its ugly head any day we omit Bible reading; it is leering over our shoulders when we can't find time for prayer - and, oh yes, when we neglect to gather round us the strength of fellowship or when our places are empty at the Lord's Table. Pride laughs up its sleeve when we are difficult to get on with, stubborn rather than amenable, digging our heels in instead of being open to reason. Just as there is no way we can serve both God and mammon, so there is no way we can (openly or secretly) believe in our personal omnipotence and at the same time believe in Jesus as the Saviour of sinners.
"Pride laughs up its sleeve when we are difficult to get on with, stubborn rather than amenable, digging our heels in instead of being open to reason." That has a very significant ouch factor.
