If by "cared for" you mean prevented from making decisions freely according to our desires, then yes, there would be nothing we could do to create famine if God prevented us from making decisions freely according to our desires. God would stop anybody from committing any act that would directly or indirectly lead to famine. But we would not be free moral agents. We would be robots that were stopped and started and stopped and started numerous times throughout the day. It would be akin to children playing red light green light on the schoolyard. One minute we are eating our dinner and the next, boom we are frozen by God in our places because we were about to throw our leftovers out in the trash. One minute we are about to go to the movies, then boom, we are frozen in our place because God decides the money we were going to spend on the movies should be sent to the starving children in Africa.
God could have created a world like that. A world where many of our thoughts and acts were never brought to fruition because they would directly or indirectly lead to human suffering. But would you really want to be a puppet on a string?
Not to overcome His power, but to spoil His creation. A little leaven leavens the whole lump. In the beginning everything God created was good. He can not do otherwise. One good thing He created was man and woman in His image with the ability to make choices. What we see in the world now is the result of the choices WE MAKE.
Maybe your parents raised you to blame others, or blame your genes, or nature, or God, or whatever else for your shortcomings and failings. I was raised to be accountable for my own actions. It is called responsibility and accountability. If I foul up, I am to blame, not someone else. If I do wrong, I must own up to it. If I complain about human suffering, and then turn a blind eye to it when I see it, I am a hypocrite.
The amount of complaining and crying that goes on here staggers me. Like you or anyone else is so concerned about people suffering. How is that the ratio of Christians to atheists is so staggeringly unbalanced when it comes to those in third world countries who are taking care of the needy?
