Consider this - you just delivered a baby but... whether this one is elect or not you don't know. Suppose this one is not an elect.... then are you saying - no matter how much u try to convince this child of yours to believe, he/she will not... even to old age and death. Why was this child even born then.. It would have been better if it were never born.
You have a child that no matter how hard you, and anyone else tries, will never be saved. In either scenario, that child came into the world with God knowing that He would have to pour His wrath upon your child.
All you are seeking to do, my friend, is get God off the hook by saying, "Hey, at least God tried to save my child." FYI, God has never tried to do anything, my friend.
