Our own sense of superiority logically requires that everybody else be inferior. And pride is most ugly when it shows up in a religious person. Turn to Luke 18 where Jesus tells a powerful parable. For everyone who exalts himself will be humbled, and he who humbles himself will be exalted. Pride destroys our relationships with others in our family, at work, at church.
Pride always ends up hurting other people.
This Thanksgiving say thank you to people around you. Don't take them for granted. The implications here are things that belong in God's court, not mine. Remember, this is a king speaking these words. Even kings should know their limitations.
