Therefore, free will implies that we have the ability not to sin. The moral government of God everywhere assumes and implies . . .the natural ability of men to obey God. Every command . . . implies and assumes this. Argument from Reason Remembering the point in question is not what we actually do, but what we're able to do. To believe in natural inability is to believe that we must sin.
Reason revolts against such an idea.
If we must sin, then we sin either by force or by accident. We cannot be held accountable for what we are forced to do or for what is purely an accident. And do you want me to believe that God is going to send millions into a burning lake of fire for something that they could not help. Natural inability means that they could not help but sin, and for this sin they are punished for ever. But reason does hold us morally accountable for our sins, therefore our sins are not forced nor accidental, but voluntary.
