Jealous? Yes, God says I am a jealous God. He is jealous for those whom He loves, that they would respond to His love. It is a perfect response to the lovelessness He is often greeted with as it does not go off and plot evil in response, but continues and continues and continues to...pursue the object(s) of His affection.
Moody? Dictatorial? Mercurial? These are the same conclusions as those of the unrepentant offender who, being sentenced by the judge, has not one moment of introspection whereby he examines himself under the full light of the law and finds the human failing, human weakness, and potential for human depravity that infects us all (his error being that he gave in to these.)
No. God is holy, righteous, glorious. I can find only one word that begins to define these in a way that the human mind can comprehend: Christ.
So he’s compassionate enough to forgive us for being exactly what he made us to be eh? Wow, he just sounds better all the time.
