Isa 25:4 For thou hast been a strength to the poor, a strength to the needy in his distress, a refuge from the storm, a shadow from the heat, when the blast of the terrible ones is as a storm against the wall.
When we look at our world the way it is today, it is very hard to see the goodness and mercy bestowed upon anybody. There are many who question a God that allows suffering. There are many who have lost their way. There is so much evil out right.
It is easy to see the dark side. What believers know is that God will never leave or forsake them. Jesus suffered for all of us. Suffering was not eliminated when he died. Evil did not go away when he died. Disasters did not go away when he died. Jesus died to save our souls. To keep the believers from hell and damnation. To allow us to go to heaven to be with our Lord. Nothing more. You cannot convince a non believer because they question the divinity of it all. It comes down to what you know and feel inside. Your own God experience. And that experience is like no other that you have ever felt.
