Matthew 6:19-21
"Do not store up for yourselves treasures on earth, where moth and rust consume and where thieves break in and steal; but store up for yourselves treasures in heaven, where neither moth nor rust consumes and where thieves do not break in and steal. For where your treasure is, there your heart will be also." (New Revised Standard Version)
A teacher I've had in my life used to tell the story of how he read mystery novels. When he would get his new book, he would sit down in his comfy chair, turn his reading lamp on, and proceed to read the last chapter of the book. He would read how the story ended, figuring out the 'who done it' and only then would he turn back the pages beginning with chapter one, reading the entire book, from start to finish. As he told his story, he explained that whenever he had worry, uncertainty or confusion as he read the book from start to finish - he always knew how the story ended.
So it is with following in the footsteps of Jesus. So it is when we think what it means to 'live like you were dying.' The last chapter has been written by Jesus death on the cross and victory over the grave. This last chapter is your last chapter - Jesus has defeated the grave for you. You need not fear death. Now that you know this, go back to the first chapter and start writing your life. Whenever you face worry, uncertainty or confusion - remember that you know how the story ends! Life always has the last word!
As you anticipate eternity - may you be given great courage to embrace today - to it's fullest.
