Yes, there were places in the Old Testament where God allowed a lot of death. However, IMHO, that did not mean He didn't value life. People sinned against God without remorse and He did destroy them or allow them to be destroyed
The Old Testament God destroys that which he values? LOL! If he really cared for those who sin he would have helped them "get back on track" so to say. Instead, he has them destroyed.
But the New Testament also tells us that God values all life and wants everyone to come to Him
What you are saying is that God wants all men to want to come to him.
But if they don't? Oh well! That doesn't sound like he really wants them to come to him. I think it would be more correct to say that God values only those who come to him. The rest can go to hell, no pun intended.
Your thinking is really almost anti-God. You sure give us a real clue into your view of God and christianity. Thanks, but no thanks.
