Man’s fate is not purely controlled by God. God created man perfectly and gave him the knowledge of good and bad. The onus is on man to choose any path. If man chooses to follow God and obey his commandments, God will be in total control of his fate. Man can control his fate by choosing the path he wants to tread in life. Some people give their lives over to occultic powers which will eventually control their fate.
Some people also are into spiritism and their fate will controlled by demons or other supernatural powers. There are people who fall into satanic territory by the company they keep and fall victims of satanic manipulation.
So, God is not totally in control of man’s fate. Man’s fate can be controlled by God, man or nature.
