Also in John 17: 5,24 - "Father, glorify me in your presence with the glory i had with you before the world began...the glory you have given me because you loved me before the creation of the world."
God is love. With that, we were given His Son, who died on the cross (displaying the greatest love of all) and through Him, we're able to have that relationship with God. We can't get to the Father unless through Christ, who beared it all. He wanted us to have an eternal union of love and life.
