The premise of this objection begins with 2 wrong assumptions. Number one is the idea that God is "All Love." This is a common teaching in the modern church. This gives people that Idea that god does not hate or get angry. when in actuality scripture tells us differently,
Deu 12:31 "... for every abominable thing that the Lord hates they have done for their gods, for they even burn their sons and their daughters in the fire to their gods. Psa 5:5 The boastful shall not stand before your eyes; you hate all evildoers.God does hate, He hates sin and the sinner and God will punish them with eternal Hell yes God does send people to hell but not ANY of HIS children. You see the faulty assumption is that ALL are children of God. The bible tells us that we are actually children of wrath and of the devil.
John 8:44 "...you of your father the devil...", Eph 2:3 "...were by nature the children of wrath"So we are actually born what Hebrews 12:8 calls "illegitimate Children" and we only become actual children of God when we repent and put our faith in Jesus Christ.
John 1:12 "But to all who did receive him (Jesus), Who believed in his name, he gave the right to become children of God"So the next time someone says something like, "I don't think a loving God would send any of his children to hell?" Say "Your right he doesn't send his children to hell! He only sends children of the devil to hell!" This gives new meaning to the phrase "Who's your daddy?"
