There is one theme that often appears in movies and novels.
That theme is about the battle between good and evil.
So, there is the main plot and also other sub-plots that will make the story more interesting.
As the story unfolds, the evil will get the upper hand over the good.
But in the end, it is the good that will triumph over the evil, and evil would be eliminated or destroyed.
That is also the theme of the 1st reading as evil seems be overpowering the saints of God.
But at the end of the 1st reading, the power of evil is stripped and utterly destroyed.
Also, God is triumphant, and His sovereignty is an eternal sovereignty and every empire will serve and obey Him.
But to believe that good will triumph over evil, then we must keep our faith in God and trust in Him.
Jesus warns us with these words: Watch yourselves, or your hearts will be coarsened with debauchery and drunkenness and the cares of life.
Let us stay wake with faith, praying at all times for the strength to face the temptations of the evil one, and to have the confidence that Jesus will save us and we will be victorious over evil.
