In the context of Christian eschatology, "mockers in the last times" refers to a specific group of people who will appear during the end times, characterized by their ridicule and dismissal of Christian beliefs, particularly the belief in the Second Coming of Christ. This concept is found in 2 Peter 3:3 and Jude 1:18, where the apostles Peter and Jude warn of such individuals who will follow their own desires and scoff at the truth.
