Moroni 7:30

For behold, they are subject unto him, to minister according to the word of his command, shewing themselves unto them of strong faith and a firm mind, in every form of godliness.

Angels obey Christ. They help people when he tells them to. They show themselves to people who have strong faith and a firm mind. They come in every form of godly service.

They obey Christ’s commands and serve people, showing themselves to those who have strong faith and firm minds, in every godly way.
