I know this can be a “thorny” question and if anyone tells you that the answer is simple, I would have to disagree. There are a lot of implications in this question, necessitating a number of things that need to be considered. I am of the personal opinion, that with the exception of Jesus Himself, no one, no one, has ever been perfectly without sin. And because of the implications that are addressed within the following multiple links, I personally believe that no one will ever, while residing in these bodies that we inhabit, upon this earth, prior to Christ’s return, be without sin.
My reasoning is contained within the links below. The multiple links are necessary because of the scope contained within the title question. For those who may disagree, my opinion is my own and we can respectfully agree to disagree. For those who may take into consideration what this detailed study encapsulates, I hope this study helps.
Our bodies still die because as Christians we still sin.
Our bodies still get sick because as Christians we still sin.
Our bodies still degrade over time because as Christians we still sin.
There is only one man in the history of the world who died and did not sin and that is Jesus.
And God (Father, Son and Holy Spirit) raised Jesus from the dead. Jesus is our hope.
We all die unless we are taken up into heaven by God before we die, or are among those who are alive and taken up during the rapture.
Why do Christians still have to physically die?
Post Note: If you have read through the comments on this post, you will note that there is some discussion pertaining to the correct focus or goal we Christians should have, of continually moving forward in Christ. And I believe that the discussion of this focus that was raised is valid because as Christians we do not continue to deliberately live in sin, and we do indeed endeavour to walk in holiness and in righteousness and we have or should have ceased from deliberately living in sin. But there is a difference between habitually living in sin and acknowledging the sin that still resides within us and so easily besets us. While our perfection in Christ is our continual goal, it is a goal that none of us will achieve while we are here in these bodies, because of sin that still resides within. Having died with Christ to sin, we have indeed have been raised with Christ, to walk in newness of life in him, so that this body of sin might be brought to nothing, because we are no longer enslaved to sin, but rather we are enslaved to God. Sanctification is a process whereby we are set apart, to function as intended by our Creator. I personally call sanctification, the onion process, because the closer we come to God, the more and more we become aware of the layers within, that this sin within touches. These layers touch on our motives, our self pride, our self centered desires within, if you will. Most of us acknowledge that there are layers within us that still need to be brought into this sanctification process. What also is true is that most of us are not aware of how big this onion actually is, nor the multiple layers that lie within. Our goal is not abandoned but neither is our acknowledgement that our perfection has not yet been completed. Two sides of the same coin.
Worthy is the Lamb! Blessings!
