2 Chronicles 7

(I sure hate it when my first attempt to type this gets lost in the ether.  SIGH.)

Well we know that God answered Solomon's long consecration prayer by sending fire down on the whole sacrifice and burning it up.  Then the glory of the Lord filled the house.  So the consecration is over.  God has blessed his house.  No one could enter the temple anymore, God's glory kept them out.
How did God's glory keep them out?  We are told them it was like a cloud.  One can move through a cloud, at least physically.  But God's holiness, God's righteousness causes such shame that unholy man feels unable to move towards, even to raise his head. Is it different in the age of Jesus' forgiveness? 
The people responded by bowing low and giving praise to God for his lovingkindness.  His faithful love is everlasting.  This is an appropriate response.
We are told Solomon sacrificed 22,000 oxen and 120,000 sheep (7:5).  Some will find it hard to belief that there were even that many animals in the whole land of Israel.  They do not believe enough people to keep or produce that many animals.  But later the writer describes all the people gathered here and describes it in terms of area where they are staying.  This area is pretty big and implies a very big crowd, millions.  These sacrificed animals will make a pretty large feast.
Solomon spent seven days consecrating the middle court and seven more days consecrating the altar.  All the people came.  It was an enormous assembly.  I tend to believe these numbers.  But I know that Chronicles was written after the version given in 1 Kings.  From a distance of time things might get distorted, perhaps inflated.  However I do not believe anyone meant to lie.  They meant to tell the truth to the glory of God.
God responds by saying, "I have chosen and consecrated this house (7:16).  God is actively involved.  God describes this present covenant.  It is conditional.  God will bless his chosen people if they continue faithful.  They must continue to worship God but also to live righteously, as God lives.  God also promises to correct and punish his people if they act unrighteously and worship other Gods.  I suppose the writers already knew what happened.  It sort of seems that the people being unfaithful was a foregone conclusion.
But God promises to forgive their unfaithfulness if they humble themselves and repent.  God promises to be the big man.  No matter how much we offend God, God promises to forgive and take us back.  Surely he knows as he takes us back, that we will do it again.  God promises that we can be faithful, but our experience gives us little comfort that is true.  We believe it only by faith..
Solomon's dynasty is also contingent on his descendants staying faithful. not worshiping other gods and leading the people into worshiping other gods. The writer likely is writing this from exile or from the experience of having to build a second temple after the first temple is destroyed.  Solomon was promised God would be faithful if he and his descendants were faithful.  But the unfaithfulness started at the end of his life and continued with his sons.
