Identifying with David is dangerous. It has already cost the priests at Nob their lives, and now the people of Keilah are threatened by Saul for harboring the fugitive he seeks.
But our of the evil of Saul's actions at Nob, God has provided David with the gift of an intercessor in Abiathar.
Christians also know that identifying with Christ is dangerous, but He himself is our mediator and intercessor against the threatenings of an evil world.
