For the upright will live in the land,
and the blameless will remain in it;
but the wicked will be cut off from the land,
and the unfaithful will be torn from it." Proverbs 2:21-22
This is the NIV translation. The land seems like it is the land of God, which might symbolize heaven. So how is the eternal security doctrine defended in light of these verses? Do these verses not count because they are in the Old Testament? Thanks.
