Greetings.....to your question " how does GOD express vanity"..?
ther ar so many stories/parables that JAH gives I as a man....I would not even know where to start.....
How bout SoloMan ? did he not turn from GOD/
how bout David ?...thinking he could kill Uriah to marry Bethsheba ?
EveryThing becomes vanity !!!
Building a tower to reach da Heavens....Nimrod....Man thinking he can be GOD
How bout ATUM

eating of the tree of knowledge ...it all becomes ONE sin
Moses asked GOD what should I do woth da man who picked up a few sticks on da sabbath....GOD said to KILL him....the least is as worse as the greatest....
this is why it states in the Bible that one will be taken and one will be left...!
I as a man am guilty of allll da sins of da world....one sin is da same as da other ...dey all interfere with each and conflict into one sin
Love
Peace be with you
Michael
