10. _Be cautious in the formation of intimate friendships._ Christians should always regard one another as friends. Yet peculiar circumstances, together with congeniality of sentiment and feeling, may give rise to a personal attachment much stronger than the common bond which unites all Christians. Of this, we have a most beautiful example in the case of David and Jonathan. This appears to be a perfect pattern of Christian friendship. They both doubtless loved other pious people. But there was existing between them a peculiar personal attachment. Their souls were "_knit together_." Friendships of this kind should not be numerous, and the objects of them should be well chosen. Long acquaintance is necessary that you may be able to repose unlimited confidence in the friend to whom you unbosom your whole heart. Form no such friendships hastily. Think what would have been the consequence if David had been deceived in this friend. He would most certainly have lost his life. 11. _Before going into company, visit your closet._ Pray that the Lord would so direct your steps that you may do all things for his glory; that he would enable you to spend the time profitably to yourself and others; that he would keep you from evil speaking, levity, and foolish jesting, and every impropriety; and that he would enable you to exert a religious influence over those with whom you may meet. Be assured, if you go out without observing this precaution, you will return with a wounded soul. Your affectionate Brother. LETTER XVI. _Charity._ "Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up, doth not behave itself unseemly; seeketh not her own; is not easily provoked; thinketh no evil; rejoiceth not in iniquity, but rejoiceth in the truth; beareth all things, believeth all things, hopeth all things, endureth all things."--1 Cor. 13:4-7. MY DEAR SISTER: Although I have often alluded, in the course of these letters, to the work of the Holy Spirit, and his blessed fruit in the heart and life, yet so deeply do I feel impressed with the excellency and amiable sweetness of the grace of _Charity_, that I feel constrained to commend it to your notice in a separate letter. Charity is the queen of the graces, excelling even faith and hope, and enduring when all those gifts which add brilliancy to the character shall cease their attractions; and, though you may not possess great personal charms, superior accomplishments, or great powers of mind, yet if you do but "put on charity," you will, like the blessed Saviour, "grow in favor both with God and man."
