Eschatology is the study of last things. Everyone has an eschatology, even atheists. Bertrand Russel said humanity is destined “to extinction in the vast death of the solar system” so you should build your life on the “foundation of unyielding despair”. Christianity offers something infinitely better. Sadly many Christians, especially young Christians are functionally agnostic about the return of Christ. In today's teaching, Nolan Tjaden makes a case that Christ's return is not a sleepy doctrine for religious debate but a seismic truth that awakens the hearts of the spiritually dead.
