Romans 8:13 : For if ye live after the flesh, ye must die; but if by the spirit ye put to death the deeds of the body, ye shall live. It is certain that the death here mentioned is spiritual death, for we shall die physically, no matter how we live. To live after the flesh results in spiritual death. All the arguing that an advocate of the impossibility of apostasy can do cannot change what Paul says. A person must accept it or reject it he cannot explain it away. But if the spirit gains the ascendency and subdues the flesh and makes it serve God, we shall live.
