“Then the King will say to those on His right, ‘Come, you who are blessed of My Father, inherit the kingdom prepared for you from the foundation of the world.’”
Jesus stated: “‘In My Father’s house are many dwelling places; if it were not so, I would have told you; for I go to prepare a place for you. If I go and prepare a place for you, I will come again and receive you to Myself, that where I am, there you may be also.’” (John 14:2-3)
Calvinist, John MacArthur, explains: “The Lord designed His kingdom from before the foundation of the world and He designed who would be in it from before the foundation of the world. And you and I are saved and we know the Lord Jesus Christ because God chose us before the world ever began. What an incredible reality!” (Understanding Election, emphasis mine)
“Since the foundation of the world” signifies the time from Abel to Zechariah (i.e. from Genesis). Otherwise, you would have the blood of Abel spilt from before he was born, that is, from before the foundation of the world.
