Exodus 12:13, 21–28, “The Blood of the Lamb”

God’s holy presence is a danger to people stained by sin and death, and no sincerity, effort, or moral improvement can make us fit to stand before Him. In the Passover, God teaches that only the blood of a substitute life can cleanse what death has defiled, so that judgment passes over and God can dwell without destroying. This same logic is fulfilled in Christ, whose blood both saves us once for all and continues to cleanse us as we walk in the light.
