The name of the LORD is a strong tower; the righteous runs into it and is safe. A rich man’s wealth is his strong city, and like a high wall in his own imagination (Proverbs 18:10-11).
The righteous person (one who is a follower of Christ) knows that his/her safety in all of life is in God who is all powerful and loving. The Lord to whom we can run to at all times for protection and care. The rich trust in their riches and their possessions, but these fail because only in God is true security.
