The slaves were to be set free (Jeremiah 34:8-9). The setting free of slaves is a form of imagery which is used in Scripture to declare the wonder of God’s saving grace. We do not deserve to be set free, yet, in grace and mercy, the Lord saves us (see Paul’s testimony in 1 Timothy 1:12-17). Through His wonderful grace and boundless mercy, the Lord gives to His people this joyful testimony: “I will walk about in freedom, for I have sought out Your precepts” (Psalm 119:45). Freedom is not only God’s gift at the beginning of the Christian life. It is His blessing throughout the Christian life, as we walk in His way.
