We tend to fail to bear pains as human beings and end up denying the existence of God. If it was for us as human beings our great grand parents would be still alive.
I had attended so many funerals for God fearing persons and non God fearing persons and there’s one thing in common, they wish their relatives could have not died. They start crying from the first day they heard the bad news of passing on of their family member up until the burial day.
Some start pointing fingers to other people accusing them of witchcraft. They put blame on God for favouring the wishes and actions of witchcraft people. Some would say God does not exist, if he existed he would have not allowed their family member’s life be taken away. 
I remember watching the movie titled God is not Dead, there was a lecture who was telling all the students to write God is Dead and if they object that they would have to support their statement and if they fail to come up with something portable he would expel them. Only one student who managed to face him and I found that the lecturer was angry because God did not save his mother’s life who was sick.
I took it as a human error to put blame on God when things does go according to our wishes. Suffering and deaths is part of life and we should all learnt to live with it. Unnecessary anger and hate towards God should come to an end.
