The premise of the tweet below is simply false. The God portrayed in the Old Testament shows love (hesed) to people constantly. Read Hosea. Read Exodus! And the God portrayed in the New Testament can get as angry as he pleases. Read the Gospels (with their many references to hell and judgment). Read the book of Revelation!
This false dichotomy has been around too long and casual readers of the Bible need to stop acting as if it were legit, because every time they do, they put their ignorance on full display.
