People have been asking this question for many years and they will go on asking until Jesus comes. If God is love why then are many suffering in pain, accidents, losses, death and sickness? We have never found a complete satisfying answer but the bible tells us several helpful suggestions.
All this happens because of the consequence of Eves disobedience. We have different types of suffering.
We may suffer as a result of ignoring basic laws. Galatians 6:7.
We suffer as a result of natural disaster or accidents. Luke 13:2-3.
We suffer as a result of power in the hands of evil men. Habakkuk 1:13.
Our suffering may result of Gods remedial judgment. Lamentation 3:33.
We suffer as a result of dedication to Jesus Christ. John 15:20.
