Let's presume Calvinism is correct. Does it really matter if some people believe and teach Arminianism? 1. The same number of people will be in heaven regardless, right? 2. God decreed/ordained those of us to be Arminians, right? 3. You evangelize because "God told you to," but does he tell you to spend countless hours debating people who take "Anthropomorphic" texts at their face value? (Texts such as when Moses prays and God relents in destroying Israel) If so, to what end? You can only convince us to change our doctrine if God has decreed for it to be so, right? Is the motive to convert an Arminian the same for converting an elect who has yet to respond? If so, where is that command in scripture and shouldn't you eventually "dust off your feet" and move on in both situations? In short, what biblical mandate are you really accomplishing here?
