_Direct._ III. By all means labour to be furnished with understanding in the matters of God. For, 1. An understanding person hath a mine of holy matter in himself, and never is quite void of matter for good discourse. He is the good scribe, that is instructed to the kingdom of God, that bringeth out of his treasury things new and old, Matt. xiii. 52. 2. And an understanding person will speak discreetly, and so will much further the success of his discourse, and not make it ridiculous, contemptuous, or uneffectual through his indiscretion. But yet if you are ignorant and wanting in understanding, do not therefore be silent; for though your ability is least, your necessity is greatest. Let necessity therefore constrain you to ask instruction, as it constraineth the needy to beg for what they want. But spare no pains to increase your knowledge. _Direct._ IV. If your own understandings and hearts do not furnish you with matter, have recourse to those manifold helps that God vouchsafeth you. As, 1. You may discourse of the last sermon that you heard, or some one lately preached that nearly touched you. 2. Or of something in the last book you read. 3. Or of some text of Scripture obvious to your thoughts. 4. Or of some notable (yea, or ordinary) providence which did lately occur. 5. Or of some examples of good or evil that are fresh before you. 6. Or of the right doing of the duty that you are about, or any such like helps. _Direct._ V. Talk not of vain, unprofitable controversies, nor often of small, circumstantial matters that make but little to edification. For there may be idle talking about matters of religion, as well as about other smaller things. Especially see that the quarrels of the times engage not your thoughts and speeches too far, into a course of unprofitableness or contention.
