Psalm 78: 36, 37: “But they deceived God with their mouth, and lied to Him with their tongue. For their heart was not steadfast toward Him, nor were they faithful in His covenant.” The next three days gives us a great object lesson in the need to be faithful and consistent to God. We already saw last week how the unfaithfulness of the people led to their exile from the Promised Land, and how, in His mercy and faithfulness, the Lord still brought them home. But did the exile give His people steadfast hearts? At first, it seemed so, as we will see tomorrow.
