I FELL IN LAVA!!!.........but Im not dead?

This one time I was digging for diamonds and I found some but I fell in lava and lot all my stuff! So I cheated and gave myself some enchanted iron tools and armor. And the next day I fall in lava!.....but it didnt kill me? Im still trying to fix this glitch myself actually! Because Im not restarting a brand new Survival World! Anyways, please fix this.
