Why hasn't God struck me down?

In the last few months I have corresponded with several Christians from YA, They usually start off civil enough then threaten me with hell or other such nonsense. In the last month or so, 2 different individuals have told me that God was gonna smite me, to prove his power. (one even told me he was Jesus and was gonna do it himself) I asked for a time line and details but they refused. Well Life is great, everything is wonderful and nothing bad has happened. Where is my smiting? Is this not evidence enough that your God isn't real?
