Good questions. If I believed in Calvinism, I wouldn't worry about much - because that would mean a person was either in or out and there would be nothing they could do about it. The 'U' would be in place for an individual no matter what. But I don't believe in Calvinish. I believe in Jesus Christ and Jesus used the word 'whosoever' from time to time when describing who would perish and who would have everlasting life.
The “Why evangelism” question is one strict Calvinists trip all over themselves on.
Seems like there has been a resurgence of Calvinism lately. Not sure why.
The fact is that the Calvinists are our brothers in Christ. There is a tendency among that movement, however, to be real in-your-face judgmental. That’s when I pull out the “Why evangelism” question, just to back them off a bit.
