How do you experience the redemption talked about in Romans 3:24?

Les teaches that God lost us when Adam fell, so He must redeem us, and He redeems us with blood—the only thing God can use to purchase mankind's redemption. Les explains that there is only one way to experience the redemption of Romans 3:24: putting your faith in the blood of Christ. In Romans 3:25, Paul speaks of Christ Jesus, whom God sent forth to be a propitiation through faith in His blood. Les connects this to the Passover night in Egypt, saying it is the same setting. Just as the Jewish family in Egypt was safe and the death angel could not touch the firstborn because of the blood on the door, so also for you and I who have had the blood of Christ applied, nothing can touch us. He then refers to Romans 8:37-39, where Paul says we are more than conquerors through Him who loved us, and that neither death, life, angels, principalities, powers, things present, nor anything that could yet come on the scene, nor height, nor depth, nor any other creature can separate us from the love of God in Christ Jesus. Why? Because we are under the blood. No power on earth or in heaven can take us from under that blood protection. As surely as the Israelites were safe in Egypt, we are safe today—a beautiful security.
