What is redemption according to this teaching?
Redemption is illustrated as buying back a mortgaged house and paying off the debt to free it from the banker's control. In Romans, it is being justified freely by God's grace through the redemption. This shows redemption as a payment that releases what was held under obligation.
Les teaches redemption using the example of a mortgaged house: the banker has control, and you cannot do anything with that house until you settle with him. But you can get the banker out of your hair by buying the mortgage back and paying it off—that is redemption. He then turns to Romans chapter 3, where Paul writes that all have sinned and come short of the glory of God, but believers are justified freely by God's grace through the redemption. Les highlights verse 24, where the word 'redemption' completes the thought.
