well firstly it's a parable, and you do what a lot of con-preachers do, take the passage out of context to make a pretext (thinking of joel osteen et al 'prosperity gospel yeah!')

however, the bible is very clear - those who do not repent, get with God, realise how fallen they are but that God made a way for all our sins to be forgiven and we could start again with a new heart and a new mind living forever with no disease or suffering, are going to suffer some horrible plagues as described in revelation 8,9,15,16 mainly.

now if God was doing this without warning He would be a monster. but the fact that He's given everybody 2000 years to get their heads right, that He is patient and long-suffering, despite what men are doing to other men, and the horrendous crimes to His children He has suffered, He still gives everyone the chance to realise the truth.

fair?
