We are tackling Isaiah 42 this Wednesday night.

Question:  why the similes in Isaiah 42:13?

The LORD shall go forth as a mighty man, he shall stir up jealousy like a man of war:  he shall cry, yea, roar; he shall prevail against his enemies.

Questions:  Is Jehovah just a pure, spiritual, divine man prevailing against other man enemies?  Why would God use the simile of a warrior man if He is already that in spiritual essence?
