what kind of sickness? the prayer I just did might be weird but it worked I know at least once, I have a nephew that was sick for 3 weeks and I ask God if someone must have this sickness then please give it to me so I can endure it instead, my nephew got better and I got sick........I miss my nephew, him and his parents had to move far away and he was the only thing that kept me happy during this long depression I have with Life...........
