Proverbs 11:2 (NKJV) — 2 When pride comes, then comes shame; But with the humble is wisdom.
After pride, shame. The proud person will surely be brought to shame. Wisdom will not be found with the proud, but with the humble. But while we should not think of ourselves more highly than we ought, we should not continually berate or belittle ourselves as is that were humility.
Romans 12:3 (NKJV) — 3 For I say, through the grace given to me, to everyone who is among you, not to think of himself more highly than he ought to think, but to think soberly, as God has dealt to each one a measure of faith.
