Heb 12:6-8, For whom the Lord loveth, he chasteneth, and scourgeth every son whom he receiveth. If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth hot? But if ye be without chastisement, whereof all (every son whom he receiveth) are partakers, then are ye bastards, and not sons.
If there are those in this world that God does not chasten, then, we can conclude that God does not love all mankind.
Psalms 73:5, They are not in trouble as other men, neither are they PLAGUED (Greek=to punished) like other men.
