Because there's a lot of hateful people and they make me feel bad so I think that God should do something about their feelings of hatred.
God did do something about hatred in the world by sending his Son, the God-man Jesus, to suffer, die, and rise again, because he, the Creator, loves his human creatures. However, by and large, his creation rejects him still. Humans are fully responsible for their hatred of others, not God.
Joh 1:9 The true light, which gives light to everyone, was coming into the world.
Joh 1:10 He was in the world, and the world was made through him, yet the world did not know him.
Joh 1:11 He came to his own, and his own people did not receive him.
Joh 1:12 But to all who did receive him, who believed in his name, he gave the right to become children of God,
Joh 1:13 who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.
