I hear that from a lot of folks. They say to me, "I just don’t feel the need for Christ." As if Christianity were something that were packaged and sold through Madison Avenue! That what we're trying to communicate to people is "Here's something that's going to make you feel good, and everybody needs a little of this in their closet or in their refrigerator," as if it were some commodity that's going to add a dash of happiness to our lives.
If the only reason a human being ever needed Jesus was to be happy and a person is already happy without Jesus, then they certainly don't need Jesus. The New Testament indicates, however, that there's another reason you or somebody else needs Jesus. There is a God who is altogether holy, who is perfectly just, and who declares that he is going to judge the world and hold every human being accountable for their life. As a perfectly holy and just God, he requires from each one of us a life of perfect obedience and of perfect justness. If there is such a God and if you have lived a life of perfect justness and obedience—that is, if you're perfect— then you certainly don't need Jesus. You don't need a Savior because only unjust people have a problem.
The problem is simply this: If God is just and requires perfection from me and I come short of that perfection and he is going to deal with me according to justice, then I am looking at a future punishment at the hands of a holy God. If the only way I can escape punishment is through a Savior and if I want to escape that, then I need a Savior. Some people will say that we're just trying to preach Jesus as a ticket out of hell, as a way to escape eternal punishment. That's not the only reason I would commend Jesus to people, but that is one of the reasons.
I think that many people in today's culture don't really believe that God is going to hold them accountable for their lives—that God really does not require righteousness. When we take that view, we don't feel the weight of the threat of judgment. If you're not afraid to deal with God's punishment, then be happy as a clam if you want. I would be living in terrible fear and trembling at the prospect of falling into the hands of a holy God.
