Redemption can be thought of like a coupon. Someone else already paid for the item & gave us the coupon. Then we give that coupon to the store in exchange for the item. Jesus paid the price for our sins & gave a coupon to every person on earth. But to receive the salvation He purchased for us we have to offer God His blood on behalf of our specific sins. Jesus buys us back even if we are completely used up, damaged, destroyed, & broken. Then He makes us whole, complete, & righteous before He gives us back to God. Wouldn’t it be a shame not to exchange that coupon?
