If one truly believes this it will work a change in him. For one thing, he will lose his fear of men. He said that we were blessed when men persecuted and reviled us, and that we should rejoice and be extremely happy. The indwelling Jesus frees one from fear of death. He now holds the keys to death and the unseen.
Death sometimes creeps in on silent feet and in the darkness.
It is not always loud and violent. And we need the assurance of his overcoming power so that death will be swallowed up in victory. It is Christ within who gives us the power to overcome self. This is a greater victory than that over death, for it is victory by death and through it, the crucifixion of the old man who has dominated us. Paul describes our struggle.
