He is an on-time God

 Read Esther 6. 

The irony is incredible.  No movie script writer will ever be able to top this scene. 

Multiple things were taking place at the same time.  Only God could have orchestrated this.

1. God was preparing the king's heart for what Esther would request later that day.

The timing and sequence of events is far beyond any coincidence.  That night he could not sleep.  He called for reading of the empire's historical records.  The readers just happened to read how Mordecai saved the king's life.  The king asked what had been done to honor Mordecai. 

2. God was preparing Haman for his downfall.

One would be hard pressed to find a greater example of sinful pride in the entire Bible.  He just happened to be in the court that morning at the same time the king asked about honoring Mordecai.  His ego unleashed all of his vanity in answering the king's question.    King Ahasuerus ordered him to be a servant to Mordecai that day and at the very same time Haman the gallows had been completed upon which to hang Mordecai. 

3. God was preparing Mordecai for his promotion.

He did a good deed and was never thanked.  Indeed, he was forgotten by others but not by God.  God waited until He could use that information for a much greater purpose.  Here was a Jew, a captured slave of the empire, being paraded through the streets wearing the king's garb, led by the man who hated him. 

God is at work even when we cannot see what He is doing.

God will deal with the unrepentant sinner sooner or later.

God sees our circumstances and knows how to use them at the right time to unfold His plan for our lives.
