'Existence' in the Bible

All things came into existence through him, and without him nothing was.

What came into existence in him was life, and the life was the light of men.

John gave witness about him, crying, This is he of whom I said, He who is coming after me is put over me because he was in existence before me.

This is he of whom I said, One is coming after me who is put over me because he was in existence before me.
