why did the god of the Old Testament command his people to kill burn and destroy all the other nations and yet in the New Testament Jesus portrays God as a full summation of love and peace well this is undoubtably one of the most popular questions in The Atheist world but the answer actually lies in both the mission of Jesus and the Israelites in the Old Testament God's commands to Israel to destroy other nations were often linked to judgment against extreme wickedness that the other nations committed their wickedness included child sacrifices mass murder waging unjust Wars
and worshiping idols and because of this God selected Israel to be the perfect nation that he would use to judge and Avenge the wickedness that other nations committed also God wanted a sinless Israel as a way for his perfect son to save Humanity
