I get your point about Idols, but where you say "what is it that
we are invested in? Don't touch my ...what? Don't borrow my what? If I lost my _____ I would be devastated.
What we are invested in should be God, yes, but that means the will of God, and doing the will of God can be/mean many different things, so if we say "I'm invested in helping or working with the homeless, the elderly, disabled, or children or all those who are less fortunate" or "I'm invested in talking to major corporations about charitable giving", or "I'm invested in self-improvement in order to better serve others in some capacity" or "I'm invested in helping others with their mental health by going to school and becoming a Psychologist." or "I'm a musician and wish to help others through my music, so I'm invested in that." or, Well, I think you get my point by now, we should be invested in doing the "will" of God in our lives, and that is going to be different for each person...
Where you say "Don't touch my " " and you think we should say "God", God is not a possession for us to possess and get jealous over, we should want others to touch or share our God, trust me their enough of God go around and we should want him to "go around" and "share" him, and not be Jealous if our God shows another person attention or care... Same goes with "Don't borrow my " ", we should want God to go to others even before ourselves, so as for me, anyone can "borrow" my God, and I do not mind...
As for the last one if I lost my " " I would be devastated, I think it OK to say God, in this case, and we should say "God" in this case, although I don't think it's necessarily a sin to say if I lost my children, or mother or father or someone else you love and care about deeply, I would be devastated. I don't necessarily think it's a sin to say that...
