My point was that people are born selfish, and not in a godly way. Watch a couple of 2 year olds fighting over a toy. It comes "naturally". That is not godly coveting. They have to be taught and trained to overcome it.
Also, can you show me a scripture where "lust" is ever referred to in a positive way?
I apologize for taking so long to respond but I am busy with other things so sometimes it may be a while before I can get back to you.
As to your first statement, it is true that children must be trained to govern shellfish tendencies but, being selfishness is not in itself a sin. God is selfish over his people. He refuses to share his people and their worship with other gods.
As to your question, yes, there are many examples of the word lust being used in a positive way. The word for lust is the word ἐπιθυμία which is translated as desire, passion, lust, longing, etc. For example:
In Philippians 1:23, Paul says,
"I am hard-pressed from both directions, having the desire (ἐπιθυμία) to depart and be with Christ, for that is very much better...."
In Luke 22:15, Jesus told his disciples,
"I have earnestly desired (ἐπιθυμία) to eat this Passover with you before I suffer;"
There are many such examples of this use of
ἐπιθυμία in scripture but, I think these will suffice. There are also many examples of the word used in the negative which demonstrates not that lust is in itself evil but, that it is the perversion of lust that is evil. One such example would be 1John 2:16,
"For all that is in the world—the desires (ἐπιθυμία) of the flesh and the desires (ἐπιθυμία) of the eyes and pride of life—is not from the Father but is from the world."
