Not arguing that point at all! I happen to believe that also. I have no quarrel with Calvinism from a doctrinal standpoint. What I object to is the archaic Bible-thumping, hellfire and brimstone way it's often presented. That does not attract unbelievers to Christ. In reality, preaching Calvinism to the unsaved is to load them down with information they aren't equipped to handle, much less respond to. Even Believers choke on it! It's not the job of the Calvinist to "weed out" the wheat from the chaff, that's God's job, and His angels. Our job is to present the Gospel simply, directly, and to use words when necessary. Our lives are (or should be) the biggest part of our testimony. I am not an advocate of "scaring" people into the Kingdom...those kind of conversions don't have a high retention rate.
The fear of the LORD is the beginning of knowledge: but fools despise wisdom and instruction.
