Jerusalem sacked and genocide of Jews 70 AD.
Disobedience among God’s people, to the revealed word of God, will inevitably bring judgment. The Bible is proof. Time and again they were warned but they refused to listen. They were repeatedly overrun by their enemies in the time of the Judges, Jerusalem was sacked and they went into captivity in Babylon in 590 BC and after they rejected the Messiah their holy city was again destroyed and millions slain by the Roman Emperor Titus in 70 AD.
“For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God?” I Peter 4:17.
God chastises his disobedient children and will utterly destroy those who profess his name but are reprobate.
