Well almost everybody knows how Jesus died for our sins, but that is not the only thing he did that had love. He is merciful every day. Like if your at a roller coaster park and he gave you free tickets for a ride, that is merciful. He shows his love but sadly not everybody notices his love, and that makes Him sad. So that is why we need to be prepared for the end because we will be judged and he will count our sins. So each time he shows His love he warns us.
