A fallen sinner is totally unable to cooperate with divine grace. Everything happens according to the divine foreknowledge and will and therefore whatever occurs is, in this sense, necessary but not compulsory . Necessity does not destroy moral responsibility. Predestination is the sine qua non of assurance . God has predestined some to eternal life and others to eternal damnation.
Predestination is fundamentally paradoxical.
God preached must be distinguished from God hidden .
