Disasters and Such

Many people will tell you their opinion on whether the Lord causes or allows disasters. Well, I think what matters is what God himself says through his word. In my bible study in Isaiah, This verse really stood out to me. Is.45:7 The one forming light and creating darkness, causing well-being and creating calamity; I am the Lord who does all these. But, his word also says, Ex.33:19 And he said, I will make all my goodness pass before you and will proclaim before you my name, The Lord. And I will be gracious to whom I will be gracious, and will show mercy on whom I will show mercy. So does a merciful God cause or allow disasters and such? I would say he most certainly does according to his word and his will!!!
