Why do people only believe in God or themselves and that's it.....why don't they give meaning to suffering death and meaningless?

Belief is required for more things than you suppose. Not for acknowledging that you have a car, or a house, or a pet. But for riding a bicycle.

For thinking you can stand up and walk across the room. These actions cannot be performed by those who have never done them because they lack belief. Some people can walk across a tightrope for no other reason than they believe they can.

You believe you will wake up tomorrow when you lie down for sleep tonight. This may or may not actually happen, so it's best to get right with God before doing so: Ezekiel 18:20 The soul that sinneth, it shall die 1 Peter 3:18: For Christ also died for sins once for all, the just for the unjust, so that He might bring us to God, having been put to death in the flesh, but made alive in the spirit John 3:18: Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God. Romans 10:13: For all who call upon the name of the Lord (Jesus) will be saved.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
