Boast the cross only

Esther 1:9-15
King Xerxes asked eunuchs bring before him Queen Vashti, wearing her royal crown, in order to display her beauty to the people and nobles, for she was lovely to look at. But Queen Vashti refused to come. Then the king became furious and burned with anger.
In 483 he gives t huge feast, the climax to a sin-month display of his wealth and power. But his queen (we are not told why) refuses to play along with his wish to make her part of the exhibition.
Why?
King Xerxes became furious for Queen Vashti refused come, he felt shame before nobles and his guests.
King Xerxes like to show his honor and what he has. It is a proud man like to be praised.
Most people like to boast some nonsense matter to the world. It looks great but there are not meaning at all.
How?
Boast the cross only and be humble before the Lord. Give glory to the Lord.
