Ten times the children of Israel were disappointed that they did not leave Egypt (the world).
With almost every disappointment their life got harder and more oppressed (depression and anger).
Some gave up expecting to leave and blamed their leaders (you are wrong again).
Those who believed in and acted on the instructions about the benefits of the blood of the Lamb (Jesus' sacrifice),
first escaped the sudden destruction of death, then escaped Egypt, and quite suddenly.
Don't give up.
