A Muslim may ask:
Jesus is just a human being and a prophet. Did not he sleep, be tired, eat and even go to the bathroom like us? Does God need sleep or go to the bathroom?!
Let us go back to the computer monitor illustration.
For some technical reason, keeping the computer monitor on all the time might cause problem with it later. That is why we have screen saver or power save mode.
Let us say you have a computer or server which has to work 24/7, and there is a monitor connected to it. When the screen goes to sleep, or you turn it off, does that mean that the hardware and the software and the electricity are also off or go to sleep?
So if Jesus’ body needed to sleep, eat, rest or even going to the bathroom, that does not mean God (hardware, software, electricity) also Has such needs.
