Have you ever heard the thought that says something like “the dead don’t die until they are forgotten”? In a sense it is true that our loved ones “live on” in our memories, but we can recognize something lacking in that sentiment. Jesus though promises life in the place of death and by raising a man named Lazarus to life he showed he has the promise to deliver it. Only Jesus, the Lord of Life, satisfies our greatest need.
What do you really need right now? If you lack something you want, life goes on just fine. If you lack something you need, that presents a problem. So, to answer the question you must understand your greatest problems. We do not look at our problems to despair, but so a solution can be applied to them. The solution in Christ. In Christ, all our greatest needs are met.
