What is The Meaning of Existence?

I have thought long and hard about this question before. I have come to a conclusion that satisfies my need for an answer, yet does not totally satisfy myself yet, for I, having felt the joy of the Lord Jesus Christ, will never be satisfied until i can see Him face to face in Heaven. I live a selfish existence but I seek to live a selfless existence. I am nowhere close to this, but I persevere in hopes that God is truly changing me more and more each day, month and year. I know that life is not about me, or my existence. My existence is important but not because I in of myself am truly important in my own right. I am important because God tells me I am important. And he tells me I am important because He created me and He loves me, and that I was worth saving. My deep seeded desire stems from this. That desire is to die to self, but this process takes a lifetime and starts new every day.  I forget this often as I am overcome by what the world tells me I should care about, and my very body gravitates towards these things. But my core and my Spirit cry out for the Living God as David put it. God made me therefore I am supposed to obey him and I know I should. God also gave me free will however so I don’t have to obey him. But God also saved me and now I want to obey him. Not because I have to, not because I should, but because simply want to. And to obey him is to put away my selfish desires so that I can do what He wants me to do, whatever it may be.  I trust that He knows what is best for me. My actions don’t often show this but through some recent trials I am starting to trust that every bad thing that happens to me is used by God to define me and shape me into a person that is more like Him, if only I allow it to. These all seem like biblical answers but that’s because they are. But they still define who I am as a Christian and as a person overall. I am far from perfect, but God is slowly changing me as much as I will let Him until the day that He returns. And then the process will be complete. This is my reason for living. This is the true meaning of existence.
