What will remain behind us when we will leave this world?

This will be an extremely serious message! You can call it a message that will show the reality in a very blunt way! No restrictions in expressing that we are gonna die one day! ALL OF US..
We need also to be blunt, straight forward and to present the things very clear, so people will understand!
We are not here for ever! I know that to so many, especially very young, life seems to be without an end, and they think they posses the so called invincibility!
But we are vulnerable, we are weak, and we need God in every single second of our life!
This message will show this reality and will even go a little bit beyond
Bible verse
Psalm 103:15
New Living Translation
Our days on earth are like grass; like wildflowers, we bloom and die.
