“For I bear them record that they have a zeal of God, but not according to knowledge.”

Ro 10:2 They have a zeal of God. They were religious, conscientious, zealous. but mistaken and fanatical. For examples of their mistaken zeal, see Ac 21:27-31 22:3. Even mistaken zeal is better than indifference.
