Then you should start talking to Calvinists. Even though we know that God has determined who will be in heaven, we do not know the means by which He chooses to do it, therefore, we MUST be dilegent in telling others about Jesus. It is what we are called to do. To not do so would be sinful.
Funny how I keep trying to agree with you to no effect. These posts do not allow for long involved statements of belief that address all possible objections. Love does not insist on its own way.
