'Exist' in the Bible

and the things which the world regards as base, and those which it sets utterly at nought--things that have no existence--God has chosen in order to reduce to nothing things that do exist;

For if so-called gods do exist, either in Heaven or on earth--and in fact there are many such gods and many such lords--

yet *we* have but one God, the Father, who is the source of all things and for whose service we exist, and but one Lord, Jesus Christ, through whom we and all things exist.
