What is the relationship between predestination and foreknowledge?

As we have detailed them above, these two terms are nearly synonymous; however, a distinction may be established. Predestination or foreordination has reference to God’s overall plan and purpose whereby he eternally, independently, and certainly determines all events in his created universe by the mere counsel of his own will (Eph 1:11; Acts 4:28; Rom 8:29). Personal foreknowledge or election has specific reference to God’s predestination of individuals to salvation (Eph 1:4–5). Predestination is the broad theme of which personal foreknowledge is a part.
