He lives in us, therefore we live.  He who conquered death has promised if we believe in Him, we will never die.  We know we end up as dust.  This is not cause for despair since we believe in the Living One who was raised from the dead.  The Creator is our Savior, so death does not, and can not, have the last word.  He who made dust live by breathing into it the breath of life will make dust live again on that great resurrection morning.

Martha *said to Him, “I know that he will rise again in the resurrection on the last day.”  Jesus said to her, “I am the resurrection and the life; he who believes in Me will live even if he dies,  and everyone who lives and believes in Me will never die. Do you believe this?”  John 11:24-26 (NASB)
