I understand efficacious grace to be the grace which God affords to convert us. If efficacious grace is always effective in converting us, then God is unjust because He failed to provide sufficient efficacious grace to prevent Satan from sinning. However God isn't unjust and there is nothing to suggest we have been afforded more grace than the fallen angels over time.

Preventing Satan (Lucifer) from sinning wasn't God's Plan. God created Lucifer knowing that he would sin because it was necessary to God's Plan. Chew on that a while....

"knowing that he would sin because it was necessary to God's Plan."

If you sincerely believe God's design of all things was to create sin, then you have things backwards. Now can you chew on that, and rephrase yourself so that the public isn't misguided to believe your implication that God condones sin to promote His Will.
