Strong's is not a good concordance to use. It is a backwards translation from KJV. So, you are getting 16th century definitions and theology. In 400 years, we have learned a lot - like that appolumi means "ruin, destroy" (BDAG) NOT "destroy completely."
That is why I so utterly detest theology by word searches. You need the very best lexicon, but you need about 20 other sources.The Greek exegetical commentary I mentioned, for each passage, he has over a 100 different sources, that he has read, and looked for agreements and disagreements. He quotes them, and tries to flesh things out, but without saying his own opinion. That is the kind of sources we need to look at, not Strong's or some internet teacher, quoting Strong's or something else.
I know that Brown-Driver-Briggs BDB the top Hebrew lexicon can be found on-line. I have a copy on my desktop on my old computer. Not sure about BDAG. I'm getting Accordance, I believe, with my course, which has a lot of good resources.
Well...I figure if a man can only kill my temporary body but God can kill both my body AND my soul, then that's a pretty total destruction. If a man kills my body, I will get a new one from God but what can a man give in exchange for his soul?
