David takes us from the wickedness of the wicked to the goodness of God in a single Psalm. One of the most beautiful things we see about God's holiness in this Psalm is how he blesses our sacrifices with and abundance only a God who is above all else and all others can. 

When we acknowledge his holiness and sacrifice our own desires - when we sacrifice self because he is holy and deserving of sacrifice - what does he do but pour out abundance on us! This again serves to solidify what he says about himself and what we only partially understand - he is holy.
