This verse directly answers your question.
1 John 3:8 He that committeth sin is of the devil; for the devil sinneth from the beginning.
For this purpose the Son of God was manifested, that he might destroy the works of the devil.
That does not mean everyone will automatically be saved, Matthew.
Some of the works of the devil are that all creation has been subjected to frustration, put in bondage to decay, and subject to groaning as in the pains of childbirth.
Rom 8: (NIV)
20 For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it [the devil], in hope
21 that the creation itself will be liberated from its bondage to decay and brought into the glorious freedom of the children of God.
22 We know that the whole creation has been groaning as in the pains of childbirth right up to the present time.
23 Not only so, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for our adoption as sons, the redemption of our bodies.
One day Jesus Christ will return and take back the control of this world from the devil (1 John 5:19). That has not happened yet. But it will.
