God apposes pride and favors the humble

“But he gives us more grace. That is why Scripture says: “God opposes the proud but shows favor to the humble.” (James 4:6 NIV)

The Bible warns about the consequences of pride

“When pride comes, then comes disgrace, but with humility comes wisdom.” (Prov. 11:2 NIV)

“Pride goes before destruction, a haughty spirit before a fall.” (Prov. 16:18 NIV)

“Do you see a person wise in their own eyes? There is more hope for a fool than for them.” (Prov. 26:12 NIV)

“Where there is strife, there is pride, but wisdom is found in those who take advice.” (Prov. 13:10 NIV)

“Before a downfall the heart is haughty, but humility comes before honor.” (Prov. 18:12 NIV)

Don't boast about yourself!

“This is what the LORD says: “Let not the wise boast of their wisdom or the strong boast of their strength or the rich boast of their riches.” (Jer. 9:23 NIV)

Put others above yourself!

“Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves.” (Phil. 2:3 NIV)

"For pride is spiritual cancer: it eats up the very possibility of love, or contentment, or even common sense.” C.S. Lewis
