I find it incredibly cruel that God's plan for man's redemption allowed his Son to hang on a cross.
My God did not cause the deaths of all these people. But, in a way known only to Him, He can use the sinful acts of others to draw men to himself. This is all part of God's plan. Free win. God's plan. It's not something any of us can comprehend......but it's far too simplistic to say that we are now under a new covenant, and therefore, God does not allow Satan to act as he did in the time of Job. Paul is very clear that Satan is acting on the earth in the New Testament.
God DOES judge the nations! Assuming for a moment that this is true, what does that mean?
You assert that something is true, then you ask me what it means?
What does it mean to you?
BTW, God judges individuals, and individuals bring judgement on themselves by their actions.
