What about sharing the gospel to the unregenerate? Obviously, you cannot say to the person that Christ died for him because he may be one of the reprobate for whom Chirst did NOT die. Doesn't sound like "good news" to me - to you? Imagine Paul or Peter preaching to the people and saying that Christ died for the elect only. There's not much hope for the unconverted:
* Am I one of the elect or not? * Did God elect me to salvation or excluded his saving grace from me, deciding not to enable me to come? * Let me repent and believe to make sure I'm one of elect. * Oh, but what if I have repented but not truly been regenerated because God had already decided that I should be one of the non-elect. * Oh, oh, why this dark decree?
The good news is that Christ died for our sins (1 Cor. 15:3), for all (2 Cor. 5:14), and for the world (1 Jn. 2:2). This is why Peter could say that the "Prince and Saviour might give repentance and forgiveness of sins to Israel" (Acts 5:31) - not just a few Israelites, but all the people.
