You are surmising that the act of returning to the father was merit.
If this work was required to be resaved as his son, then yes, it is a work of merti.
its obvious you do not understand what works of merit are.
You are not quoting merit you are surmising merit. Merit is not in your example.
Can you not see the difference?
I am not surmising anything
I am stating a fact.
Also. the fact the child NEVER stopped being the son. He did not have to come back to continue being a son HE WAS STILL A SON.
He had his fellowship restored. he never lost his sonship.
either way. I showed someone who was trying to merit salvation. I did what you asked.
