When you introduce someone to the offer Jesus made you're not offering something better in the sense of "this microwave is better than that one." Which is how many in our postmodern world feel. They think you're arrogantly saying Christianity is better. But that's not what you're saying. Because in such an illustration either microwave may indeed work, the only difference is one is superior in the number of features, or the speed of cook time, or cost to take home.
With Jesus it's completely different because nothing else works. Nothing else is even remotely comparable.
Or to carry out the analogy, nothing else can even begin to heat up food. Everything else you put the food in to poisons and kills you.
