If Jesus Christ was who He claimed to be, and He did die on a cross at a point of time in history, then, for all history past and all history future it is relevant because that is the very focal point for forgiveness and redemption. ↗
Here's the simplest answer: Within weeks, the disciples proclaimed the resurrection of Jesus Christ, that He had been bodily raised from the dead and appeared to them. ↗
Jesus claimed He had the power to raise himself from the dead and His followers would be raised from the dead. That's a unique claim in the literature of religion. ↗
When Jesus then is with the multitudes, He is not in His house, for the multitudes are outside of the house, and it is an act which springs from His love of men to leave the house and to go away to those who are not able to come to Him. ↗
We should be recklessly abandoned to Jesus, and just turn it over to Him. Through the support I think the sacrifices will be made and we'll all be cool with it. ↗
