He couldn’t have been further from the truth.
The Bible states clearly that human beings are mortal and no one will receive immortality until the the time of the resurrection at the second coming of Christ (John 5:28, 29, 1Cor. 15:51-55).
Better that we follow the teaching of the Apostle Paul who said: “For I am already being poured out like a drink offering, and the time has come for my departure [death]. I have fought the good fight, I have finished the race, I have kept the faith. Now there is in store for me the crown of righteousness, which the Lord, the righteous Judge, will award to me on that day—and not only to me, but also to all who have longed for his appearing.” (2Timothy 4:6-8).
“That day” is, of course, not the day of his death but the day of Christ’s appearing when all the faithful will receive their reward.
