When the bottom has come out of our life, when we meet our Gethsemane, where does inner strength come from? The Apostle Paul wrote to the Philippians that he had the “secret” to be content in every situation. He said God gave him strength to face “all things”. But in that text he never explains what the secret is! This week we look again at the Christian source of strength and Paul tipping his hand to what the “secret” is in Ephesians 4.
