One thing I made them think about was the growth rate of who they thought would be saved and the growth rate of who was going to be killed.
So I first got them to agree that to be saved they would have to be taught the Bible by Jdubs then I asked them how many of those there were they said around 7,000,000, . I then asked them what the growth rate was of their religion and they didn't know so I estimated way high like 10% so they could figure it out easily, neither of them knew how to figure 10% of 7 million so I had to tell them the answer then I told them there were about 3.5 billion people on the earth and it the growth rate of the earth was 10% per year, I know it's more than that but I just wanted to get the point across that the longer their God waits, the more people he's going to have to kill, I mean destroy
IE:
3.5 billion +10% = 3.5 million
7 million + 10%= 700,000
That's over 2 and 3/4 million a year more people that God is going to have to destroy. After telling them these calculations, I told them "you ladies are going to have to get busy"
