Scripture says God opposes pride because pride is lethal to our relationship with Him and each other. This theme is apparent in the book of Daniel as King Nebuchadnezzar exhibits all the symptoms of pride.
It is Daniel that points this out to the king.
One of the great dangers of pride is that the people who suffer from it tend to be the most blind to it. In order to avoid this, we must search ourselves and pray to God to reveal pride in us if it is causing problems.
If we neglect the danger signs of pride, it will become our relational downfall.
