1. He must be a teacher in knowledge.—He must know his lesson in all its departments and bearings, and with a wealth of information far greater that he expects to impart to his class; for power in teaching proceeds more from the reserve force of the things known and kept back, than from the things taught.

2. He must be a teacher in tact; that is, in wisdom, to know opportunities and skill to use them. Tact is a gift, but it may be cultivated and improved by application. And, “if any of you lack wisdom, let him ask of God, that giveth to all men liberally and upbraideth not, and it shall be given him.” James 1:5.

LESSON IV.—THE CANON OF SCRIPTURE.

The English word canon is a literal re-spelling of the Greek word meaning “a straight rod,” hence, “a rule or standard.” As used in reference to the Bible, it means:

1. The rule or fundamental principle of truth.

2. The catalogue of the books which contain that truth. As there are two testaments, the old and new, it is necessary to notice the canon of each separately, answering the question, “How came the Bible in its present form?”

I. The Old Testament Canon.—In the growth of the Old Testament we can trace six stages.

1. The Oral Period, extending from the earliest ages down to the time of the patriarchs, during which the Divine Revelation and the records of the past were transmitted by tradition, or in a few detached documents, like Genesis x.

2. The Mosaic Period (1500-1400 B. C.) When from ancient manuscripts, tradition and revelation were written the book of Job, and the earliest draft of the Pentateuch, and Joshua.

3. The Davidic Period (1100-1000 B. C.), the age of Samuel, David and Solomon, when, after the disorders in the time of the Judges, literature began to flourish anew, and Judges, Ruth, Samuel, the first draft of Psalms and Proverbs, the Song of Solomon, and perhaps (but by no means with certainty) Ecclesiastes were written.
