@Greatest I am,
You are correct in that God condoned and even encouraged some atrocities, however there is one crucial fact that has been overlooked. All of these horrors were committed in the infancy of God's chosen people, he was like a parent spanking his children to teach them. After Jesus's death and the curtains in the temple were torn, a new covenant was made and we, his chosen people, could now appreciate his love, and he no longer had to use those means. Would you say that a parent spanking their child if they ran into the middle of a busy street is unloving? No, spanking is just the most effective way of teaching. What could have happened if the child had never learned that lesson? Maybe nothing but maybe something much worse than a small smack.
We cant say what would have happened had God not decided to be so merciless, but if you believe in God, and you must if you are writing this, you must believe he knew what would have happened. How can you say the actions taken weren't the best possible solutions?
You say that people brake the first commandment by believing God is good, yet I say you are braking it by believing he isn't good. God tells us he is good therefore if we believe differently we are going against his own words and what he has specifically told us to believe about him. Against his own words how can we base our opinions of his nature on events thousands of years ago that we can't possibly hope to understand fully.
It can be said that man cannot do more about this situation than what he is already doing.
God does not have that excuse.
But that is exactly what the first statement is, an excuse. It seems obvious to me that humans could be doing much more. Each one of us has luxuries that are not essential to life, yet we keep them and let people starve. However, this is like the old testament stories in that no one can possibly know the whole picture. We cannot say how much love comes from this suffering, or how many people end up achieving eternal happiness because of the suffering here on Earth. Demanding that God change the world is actually breaking the first commandment also. It is a sin of pride, placing yourself as the idol, assuming to know better than God the best thing for all humans.
