If you believe in the existence of God, then it would make some sense to become more informed about Him. Inevitably, we come to Scriptural evidence that God has the ability to restore life to human beings. If such is the case (which I certainly believe), then human wrongs (even one's which led to the death of living beings) can and will be corrected by Him.
This obviously doesn't give us the right to destroy human life (Thou Shalt Not Kill). The Bible says that Man has dominated Man to his injury.........which is clearly the case most of the time. According to the Bible, God has not yet come to claim TOTAL AUTHORITY of the Earth. In the meantime, our governments are in charge.
In the case of the American Indians, our government was atrocious (understatement of the universe). God didn't come down and intervene because at the present time mankind runs itself (clearly, mankind has made some awful decisions as God waits to Re-assume control over His world).
This is NOT going to be a permanent situation. The Bible predicts that God will make His presence known and take over his rightful domain (Earth). When this takes place isn't known and the fact that God exists isn't allowed to be known. My feeling is that THIS is how the faithful are tested. If we all knew for a fact that God would re-claim rightful authority over the Earth, we'd worry less about mankind's obviously huge mistakes and focus on how we think, act and treat one another.
There is evidence which supports the possibility that this Reclamation of authority may take place sooner than later. There is an increasing resentment towards God's people that appears to be growing by leaps and bounds. When the world turns to destroy God's people, that is when it is said "it will be as though they are touching my eyeball".
Prophecy is even now taking place. This "people who don't like God" phenomenon has become a reality and we see religion made fun of as though it is a fairy tale on national television. People have ABUSED other: nations, cultures and races in a manner that is horrific. They will turn against God's people because they honestly do not believe in Scriptural Prophecy and because Prophecy says they will. When they raise their hand to destroy God's people, God will take back what is rightfully His. When this happens - all injustice will come to an end.
