If God really exists, and he can do anything, why is there still death, starving, pain, sadness, and conflict in this world? Because of sin. Why do you lie, steal, cheat, and commit crimes? Same. Nobody's perfect. The result of mankind disobeying God's holy word, was eternal death. If the people in the famine put their trust in Christ Jesus, they'll go to Heaven, without pain or sorrow, where the old life, the pain of starvation, will pass away. And it won't matter.
