As to style, seek only to be clear. Nothing else is important. Never try to be elegant or striking.
Consider the method of the Saviour in His addresses to the people. Next to Him, those perfect specimens of the art of putting things are the speeches and epistles of St. Paul. I know of nothing in literature so clear, convincing, and logical.
The words of the Master astonish one with their absolute unity with all the rules of effective address.
Especially His method of driving home a truth by repeating it, and that, too, in exactly the same words, is noticeable and very effective. He did not fear that He would be tiresome; He was concerned only in being clear. Take the following examples—Matthew vii:
24. Therefore, whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:
25. And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.
26. And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:
27. And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it.
Or study this—Matthew v:
29. And if thy right eye offend thee, pluck it out and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
