Romans 8:19 for the earnest expectation of the creature waiteth for the manifestation of the Sons of God. When God created the world, everything He made was good, and He gave man dominion over his creation. But when sin entered the world through Adam's transgression, death also came in and from that point on, everything in the world became subject to decay and regression. This why today everything that exists both living and no living things, is crying out for liberation. Men are groaning under the weight of sicknes, disease and poverty, money is also crying out to be delivered from the hands of the wicked. The only hope for all creation in the world is the sons of God. The word sons is from the greek word huios and it means sons raised for authority and control. These sons are those who have learned to handle the Word of God, they are skilful in use of the sword of the Spirit, they are not subject to the elements of this world, they live above the system. Understand that God is aware of all the problems the world is facing, he knows there are wars, famine, killer diseases but he is unable to do anything about it because the authority over his creation is in the hands of man. you have to understand how God operates, just because he sees all the problems, doesnt mean he will solve them. This is why the Bible talks about the sons of God( raised for control). It is these sons that can command order in the world, these ones declare the Word of God over all rebellious circumstances, and command that everything be subjected to the Word. To the sick they command healing, to the poor they command prosperity.
