Amen.. Including Adam and Eve.. Moses.. All the Prophets.. even the Apostles.. All men, faithful or not, rightfully belong to God.. Unless you mean only "christians" belong to Jesus.. Surely you don't mean that do you?.. God is rightful owner of this entire planet.. and everything on it..
The Father does not own some things and Jesus owns other things.. for they are both ONE.. The Father, Son, and Holy Spirit are one with each other.. as far as I can determine..
Only observers "in" time - sensing linear time, an arrow of time - would have a sense of a difference between the before and after Christ's being enfleshed.
God's Name is I AM.
Time is part of the creation, not a property of the Creator.
Thus, Jesus is the Lamb slain from the foundation of the world (Rev 13:8) - and He is always the Lamb of God and the Lion of the Tribe of Judah (Revelation 5). Likewise, we are chosen from the foundation of the world - just like Moses, Abraham, David, etc.
Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am. - John 8:58
As soon then as he had said unto them, I am [he], they went backward, and fell to the ground. - John 18:6
