The perfection of God...

"Remember the perfections of that God whom you worship, that he is a Spirit, and therefore to be worshipped in spirit and truth;

and that he is most great and terrible, and therefore to be worshipped with seriousness and reverence,

and not to be dallied with, or served with toys or lifeless lip-service;

and that he is most holy, pure, and jealous, and therefore to be purely worshipped;

and that he is still present with you, and all things are naked and open to him with whom we have to do.

The knowledge of God, and the remembrance of his all-seeing presence, are the most powerful means against hypocrisy."

-- Richard Baxter, English, Calvinistic, Puritan church leader. (From The Berean Call.)

Richard Baxter (1615-1691) wrote hymns and was a great leader. Two quotes might be familiar to you:

"I preach as never sure to preach again,
And as a dying man to dying men."

"In necessary things, unity; in doubtful things, liberty; in all things, charity."
