I’ve read many deep and complex quotes attempting to define humility, but from my own encounters and understanding of the Word, I realized it is actually quite simple.
Humility is acknowledging complete weakness and helplessness without God. Pride is thinking we are something apart of Him.
Man in all his pomp and grandeur is disregarded as nothing before His sight. Woe to the one who shakes his fist at God and sneers at Him, but blessed is the one who acknowledges their need for Him. He opposes the proud but He gives grace to the humble.
