Well, that is a serious question. First, let's settle on a definition of the word "sacred." This is from dictionay.com
SACRED
1. devoted or dedicated to a deity or to some religious purpose; consecrated.
2. entitled to veneration or religious respect by association with divinity or divine things; holy.
3. pertaining to or connected with religion (opposed to secular or profane ): sacred music; sacred books.
4. reverently dedicated to some person, purpose, or object: a morning hour sacred to study.
5. regarded with reverence: the sacred memory of a dead hero.
6. secured against violation, infringement, etc., as by reverence or sense of right: sacred oaths; sacred rights.
7. properly immune from violence, interference, etc., as a person or office.
Which one do you want? Personally, I hold that life is sacred, or rather, my life is sacred, in the sense of the first definition. God has created me, and my purpose for living is to glorify Him. In pursuing that purpose, I find joy, happiness, contentment and fulfillment.
Ecclesiastes 12:13 Now all has been heard; here is the conclusion of the matter: Fear God and keep his commandments, for this is the whole duty of man.
All the commandments can be summed up in two: Love the Lord with all your heart, mind, and strength; and love your neighbor as yourself.
I started my post by saying that "my life is sacred" not because I dont think anyone else's life is sacred, but because I can't speak for anyone else. I certainly hold all human life as sacred, but if sacred means set apart for God, then only each individual can attest to that for themselves. Unless, of course, you would hold to a different definition of the word sacred.
Oh, well, I just realized that the original post was almost three weeks ago, and the original poster has not replied or clarified. Maybe no one is following this post? Anyway, I enjoyed clarifying my own thoughts on the issue.
