Our Lord took on real flesh and has entered history to live a perfect life, die on the cross, be raised to life, and ascend to heaven. He gives the sure promise that those who respond to the gospel in faith have life right now and true life in the age to come. However, those who do not respond in faith do not and will not have life in the age to come. His assurance and warning is that how one responds to the gospel in this day has ramifications for the life to come. So, what is essential to the Gospel message to have life? Do we really need to believe that Christ took on the flesh?
