Most dictionary definitions of God are: “a perfect being.” Your question seems to be: is there such a being, and, if so, how can this being allow the suffering that goes on in the world? You might as well go ahead and add to these questions, “why does anyone have to die?”
I can give you the Biblical answer to the last two questions: sin and man’s sinful nature. It says, " Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for all have sinned." (Romans 5:12). In turn sinning and death produce suffering. Notice it doesn’t say “by God sin entered into the world…” The wickedness and deceipt that goes on in the world is explained by Jeremia 17:9: “The heart is deceitful above all things, and desperatly wicked, who can know it?” That, by the way, is speaking of the heart of man. Man is totally responsible for the condition of the world.
Why doesn’t a righteous, omnipotent (there’s a good Episcopalian term!) God just come on down here and correct this problem, so that death and suffering can stop? He has! He “made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: And being found in the fashion of a man, he humbled himself, and became obedient unto death, even the death of the cross.” (Philippians 2:7,8) He identified himself on the cross with our plight, and because of this God has reconciled himself to us (1 Corinthians 5:19), and now offers anyone who will receive it, salvation from the penalty of sin, and the gift of eternal life (Romans 6:7,23). You see, the world’s problem is not suffering; the world’s problem is unbelief. Folks, by and large, don’t believe what I’ve just said. But God took care of the problem by taking on the form of the man Jesus Christ, went and died for our sins, was buried, and was raised from the dead for our justification (1 Corinthians 15:3,4; Romans 4:25)
Nobel prize winning physicist, Werner von Braun, said of those who would not believe there was a Supreme Creator of the Universe: “must we light a candle, in order for them to see the sun?” Accept Christ and what he did for you on the cross, and God will light your spiritual candle. You will then be inabled to see the truth, and “the truth shall make you free.” (John 8:32)
