"One of your greatest dangers is a spirit of self-confidence and pride. The great unhappiness which exists with you and in your family results immediately from the operation of pride. The usefulness of a man who has this pride must be greatly limited, for his pride and self-love keep him in a narrow sphere. His spirit is not generous. His efforts are not extended, but contracted. By his conversation and deportment this pride will be discovered if it exists. 4T 259.1"
"Pride goeth before destruction, and an haughty spirit before a fall."
The EGW passage directly addresses the dangers and consequences of pride, mirroring the principle stated in Proverbs 16:18. The proverb is a concise statement of the same idea that EGW elaborates on.
