John Wesley once argued that the Bible is written by either good men, bad men, or God.
1. It can't have been written by good men, because good men would not have deceitfully claimed time and again, 'Thus says the Lord.'
2. It can't have been written by bad men, because bad men wouldn't have spent so much time commending virtue and discouraging vice.
3. Therefore it must have been written by God.
