The House of the LORD

What was the significance of approaching Jerusalem? Why was the blood of bulls and goats shed until Christ came? Why was a 'covering' for sin necessary? How is Christ the Testimony of God? Is worship of the LORD ever a drudgery in this flesh? Why did the LORD build these temporary 'houses' of the LORD? Where is it that God dwells on this earth in these last days? Is the LORD always the One Who gives rest? Why is God merciful to any? Was a wicked sinner such as Solomon saved?
