God can still be Sovereign and permit his creatures to make decisions to do though, and still be seen as part of His Plans and purposes, correct? As God decreed thatJesus would die on the Cross, and yet God still used sinners to accomplish that thru their decisions, not forced by Him?

The bible to me seems to be stating that in this Present age, before the second coming, There will be things permitted/allowed by God, sucj as Isis running wild for example?
