I also love when a speaker gives you insights to a word used by another time and culture. He redefined backsliding for me . In church circles you would use the word to describe someone who was a christian and now is going back into worldly living. In the original language the word was to give a picture of a donkey siting on his behind and the master is trying to pull him up and the donkey won't go.
That broadens the picture abit. It can be describing a church going nice person who is not doing what God is asking of him or her. We have some covers we hide under: like That is not my thing, I am too old, I have already given enough, I got hurt the last time, I don't like to do that, I don't think that's my calling. My favorite is " I don't have the skill for that". It is my favorite because most everything God has asked me to do I have said that. He has always said "I equip the called"
