When the orthodox Reformer says that God ordains something He means: either God directly causes something or that He permits something (evil) to happen. This isn’t God speaking with a forked tongue (whatever that means). Rather it is a truth taught in scripture. God doesn’t directly cause evil. For this would make Him the author of evil. Rather He permits it (for morally sufficient reasons) to bring about His overall plans and purposes. His permitting evil it is a kind of indirect causing. That is, His permission is a kind of secondary causing not a direct causing. For example: Satan gets permission from God to torment Job. God allowed Satan to take Job’s family and make Job sick. Yet Job says, “The Lord has given and the Lord has taken away” and “Shall we recieve good from God and shall we not recieve evil” - to which the writer responds: “In all this Job did not sin with his lips”. As Theodore Beza has stated:
When God permits evil He has morally sufficient reasons for doing so. That is, God’s intentions are good, Satan’s intentions are evil. One act - two intentions. What Satan means for evil God means for good.
