The world has come a long way. Many things have happened in between. We are not the same as we were some years back. These days, scientific knowledge and innovations have taken man way very far from where he was. We should understood that the more knowledge we gain the more troubles we are bringing to ourselves. We have advanced technologically and that makes us think that we are somehow in the position of a super power. If we have nuclear power at our disposal, shouldn't we use that resources to generate useful energy from the world? What is the essence of posing a threat to the world. The wars are not good but maybe we should allow it for a while so that some of the egos can be abated.
Well, this is a question from

Till man learn to submit totally to the will of God, there will not be peace in the world. The primary cause of conflicts and clashes around the world is because we have left God out of the issues of our lives. How can we expect to have a peaceful world when we choose to walk against the one who created the world? If anyone wants to hear my sincere mind with regards to the current warring situations in the world, i will like to say that God is perfectly in charge. As far as we choose to live as if God does not exist, we will not have peace.
What is the cause of the wars?
I want to show you what I am capable of.
Yes, that is the cause of the wars! One party wants to show the other what it is capable of accomplishing. That is just it. Because of technological advancement, some countries have developed their military power (specially with the availability of weapons of mass destruction). So, they stand up now to fight everyone and pose a threat. That is just what I am thinking.
To those of us who are here, maybe we should just pray for peace in the world. Let us pray that God will stop all these wars. Let us pray that the hearts of the leaders would be arrested by God. Please, we need to pray so that God can intervene and give us peace in the
