I'm no longer a religious man so I'll say to you what Ive said to my son when he asked what's the point of life.
We don't know whats ahead for us after death and death may come at anytime. As such we must face the world as it is seek to be worthy of any judgement we may face either of God or men.
We owe duties to our families (to protect and provide) as they were before us and will be after us. So put them before anything else (including your own survival).
Next you owe duties to your community. Protect them even if it cost you your life. Seek to make it better starting with the little things first .
Lastly you owe a duty to yourself to be as much as you can be. Seek always to improve a little each day.
If you do these things you will have nothing to fear from life or death for you will have lived well and will be ready for what ever is asked of you.
