Everyone knows that they are going to die, everyone of us knows that, the truth is, none of us believe it because if we did, we will do things differently. When I faced death, when I had to, I stripped myself off all stuff totally and I focused only on what is essential, the irony is that a lot of times only when we learn how to die then we learn how to live. I know it sounds very morbid for this morning but it's the truth. Most importantly, I think true joy comes from knowing God and not knowing about God, I mean you can read the Bible and know about God, but knowing God personally and have a relationship with God which is the most important thing. 
Death is always upon us, lets hope for a happy life !
