When God will come to earth to help us and heal this world?

God never actually leaves heaven. He can do everything he wants from heaven. God comes in a figurative sense meaning that he turns his attention toward something with the intent to actively do something. God will "come" or turn his attention actively toward the earth when he has finally gathered all the remaining humans to be true Christians. Unfortunately the world in general will continue to suffer in their ignorance of God and disobedience toward God. The time for him to intervene is extremely near. God has provided his inspired word, the Bible, that helps many people to heal today when they obey and practice its teachings. God will have to bring to ruin those who are ruining the earth through disobedience, selfishness and greed. His true followers will remain as God heals the earth. God listens only to those who obey him and do what is right according to his word. People show that they need God when they listen to him in their everyday life, not just when there is a disaster. Most of humanity ignore the Bible, which most of the world's population has or has access to and many even curse and spurn and tell lies on God. God is not waiting for anything, we are waiting on God. You can reach God through his true Christian organization on earth today along with a Bible study to help you understand God's patience and forbearance. You also need to call on God through prayer while seeking him with his human servants. In doing so you will learn why we suffer and how and when God will intervene to stop catastrophes.
