Sheep are predestined to be sheep, and goats are predestined to be goats. They don’t change their identities by exercising their own will.
you seam to be missing the point Jesus said If I am lifted up I will draw all Me unto me. The world was passing jugement upon the Son of God because of Christ's obedience God the Father gave him all authority and Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
He was Judged by the world and the world's judgment was to lift him up from the earth on a cross. God the Father lifted him up above all names now Jesus will draw all men unto him for judgment
