Hi there Thanks for the reply. To be honest, the answer was really beyond my current understanding of life. But I think gradually I will understand it. A new question: Why is there pain in the world? God has created us and there is no doubt about it. But why has He created pain , too? Why should we human tolerate the burdens and troubles of this life? Do not you think it is against God’s justice? I know that He is so kind, but I can not understand why He has created pain.  WHY?

if God at all produces any pain it is to discipline us, out of love. Otherwise, I’d say most of the pain created out there are done so by humans. In Revelations it talks about the day when Christ will rule here, but it is not like that at the moment. God works for the good of all of us but he does not control everyone like robots. He respects free choice. He definitely did not cause all this suffering.
