@Smileyrius,
I great deal of the sufferings in my life comes from my errors and my sins. God neither wants us to error nor sin. I once drank from the cup of someone with bleeding gums and was later diagnosed with hepatitis C. I had the symptom of jaundice (a yellowing of skin). I prayed to Jesus and believe that He cured me. I no longer have any trace of it nor any signs that I ever even had it.
Mark 16:17 And these signs will follow those who believe: In My name they will cast out demons; they will speak with new tongues; they will take up serpents;
and if they drink anything deadly, it will by no means hurt them; they will lay hands on the sick, and they will recover.
It is wise to try not to make mistakes or sin in one's life.
