Is There a Sea Battle Tomorrow?

Aristotle asked if it is true now that there will be a sea battle tomorrow, and is occurrence of the sea battle inevitable and hence necessary. Augustine replies by saying God knows there will be an upcoming sea battle; this changes things in two ways. He tells Evodius that it is incoherent to worry that God's knowledge necessitates anyone to will anything. Can Augustine still absolve God of blame later in his career once he has developed his doctrine of original sin against the Pelagians? According to this doctrine, I cannot be good unless God offers me the assistance of grace.
