How do the Scriptures define “death” and can a person who is; “born again and full of the life of God:” experience death?
In most cases (not all); when the Bible uses the word: “death;” it is not talking of the physical expiration date of the mortal body. For example when Ephesians 2:1 refers to us, who were “dead” in trespasses and sins being quickened or made alive; it is not saying we were physically dead before our conversion.
For further clarity, we look to Romans 8:13 which states: “For if ye (you and I) live after the flesh (or separate from the His life deposit located in our spirit), ye (you and I) shall die: but if ye (you and I) through the Spirit do mortify the deeds of the body, ye (we) shall live (or experience life as opposed to mere existence) (Emp. mine). The answer to our original question is found in Ephesians 4:17, 18 where the Holy Spirit through Paul instructs the believer to not walk as the unregenerate nations walk in the vanity of their mind with a darkened understanding.
He goes on to instruct that this ignorance, which is in them, is a result of a blinded heart. Hence they live their lives alienated or separate from God. Wow! Yes a believer can operate as the unsaved world, through ignorance. If not; Paul would have never given these instructions to the church. While it is true that God will NEVER leave us; we can through ignorance; live, as if He has, left us. Death is here defined as living alienated from God. This is why a child of God who does not realize the new creation they have become in the spirit; will end up living as a mere unchanged person who operates no different than the world around them (see 1 Cor.3:3 Amp.). Living after what you see in the flesh, or the strength of the flesh, will result in living separate from His resurrection life that resides big in your born again spirit. So reject “death” by the acknowledgement of every good thing that is in you in Christ Jesus and keep or guard that precious deposit by the Person and power of the Holy Ghost. (Philemon 1: 6; 2 Timothy 1:14). You are Blessed!
