God's omnipotence and human freedom

The relation between God's omnipotence and human freedom has been a problematic issue in Reformed theology for centuries. The question is, how can human beings be free if everything is controlled by God? And if human beings are not free, they cannot be held responsible for their acts. As a consequence they cannot be guilty. It is not a new question, as Paul in the letter to the Romans already introduces fictive opponents who argue, Why does God complain about human sin if He Himself decides everything? (Romans 9:19). In modern times, however, the question has become more acute, due to the increased awareness of human individuality, identity and freedom. For modern people the idea of an all-controlling God is an affront to humanity. Therefore they try to develop theologies that avoid this idea.
