Tasting death?

The verse comes from Mark Chapter 9; Verse 1

And he said to them, "I tell you the truth, some who are standing here will not taste death before they see the kingdom of God come with power."

I read this and ask myself many questions.  I'm the type of person that counts everything that he has done in his life, its terrible i know.  I can't help it though it seems to have stuck with me because i dont see myself in the light, let alone in Gods light.  This passage talks about Death, and when a lot of us think about death or at least for myself i think of funerals, people in coffins or the ground.  But as i read this i dont think that is what Jesus talks about.  Death in this context i feel like is the life of sin that once ruled our lives.  The reason i wrote about counting everything that i do is because i see the sin in my life, i repent but true repentence bears fruit of change.  There are certain things in my life that is so difficult for me to let go of, my pride for instance and my selfeshness and my lustful heart are things that before i was born again i had and now i still have.  I look and ask myself whats changed in my life?  Have i died?? have i really, i doubt.  I might just be feeling this way because i am kind of sad right now but its a question i need to ask myself everyday, have i died.  I need a heart that is focused on the Lord, who am i to say that i am anything.

Application; i need to die... everyday to myself.  My application for my life is that i need to pray everymorning asking for strength through persevering through the holy spirit to show me the path that i need to take. Prayer in the morning.
