Predestined definition

Predestined. - literally means “to mark out beforehand” (Acts. 4:28; 1 Corinthians 2:7; Ephesians 1:5,11)
Predestined means marked out before‐hand. This is another way of saying salvation is God’s work and not your own doing. God has adopted you as His own child. Through Jesus’ sacrifice, He has brought you into His family and made you an heir along with Jesus (Romans 8:17). In Roman law, adopted children had the same rights and privileges as natural children. This term shows how strong your relationship to God is. You belong to God’s dearly beloved Son.
Predestined in Greek is proorizo, and it means to predetermine, to determine beforehand, or to determine that something would happen in advance. We see a similar thought in Ephesians 1:11-12. “In him we have also received an inheritance, because we were predestined according to the plan of the one who works out everything in agreement with the purpose of his will, 12 so that we who had already put our hope in Christ might bring praise to his glory.” So God chose to save the elect before the foundation of the world; before creation.
