Their spot is not the spot of his children - This verse is variously translated and variously understood. They are corrupted, not his, children of pollution - Kennicott. They are corrupt, they are not his children, they are blotted - Houbigant. This is according to the Samaritan. The interpretation commonly given to these words is as unfounded as it is exceptionable: "God's children have their spots, i. e., their sins, but sin in them is not like sin in others; in others sin is exceedingly sinful, but God does not see the sins of his children as he sees the sins of his enemies," etc. Unfortunately for this bad doctrine, there is no foundation for it in the sacred text, which, though very obscure, may be thus translated: He (Israel) hath corrupted himself. They (the Israelites) are not his children: they are spotted. Coverdale renders the whole passage thus: "The froward and overthwart generation have marred themselves to himward, and are not his children because of their deformity." This is the sense of the verse. Let it be observed that the word spot, which is repeated in our translation, occurs but once in the original, and the marginal reading is greatly to be preferred: He hath corrupted to himself, that they are not his children; that is their blot. And because they had the blot of sin on them, because they were spotted with iniquity and marked idolaters, therefore God renounces them. There may be here an allusion to the marks which the worshippers of particular idols had on different parts of their bodies, especially on their foreheads; and as idolatry is the crime with which they are here charged, the spot or mark mentioned may refer to the mark or stigma of their idol. The different sects of idolaters in the East are distinguished by their sectarian marks, the stigma of their respective idols. These sectarian marks, particularly on the forehead, amount to nearly one hundred among the Hindoos, and especially among the two sects, the worshippers of Seeva, and the worshippers of Vishnoo. In many cases these marks are renewed daily, for they account it irreligious to perform any sacred rite to their god without his mark on the forehead; the marks are generally horizontal and perpendicular lines, crescents, circles, leaves, eyes, etc., in red, black, white, and yellow. This very custom is referred to in Revelation 20:4, where the beast gives his mark to his followers, and it is very likely that Moses refers to such a custom among the idolatrous of his own day. This removes all the difficulty of the text. God's children have no sinful spots, because Christ saves them from their sins; and their motto or mark is, Holiness to the Lord.

Religion --A Reality
Now we will grant you this morning that much of the religion which is abroad in the world is a vain thing. The religion of ceremonies is vain. If a man shall trust in the gorgeous pomp of uncommanded mysteries, if he shall consider that there resides some mystic efficacy in a priest, and that by uttering certain words a blessing is infallibly received, we tell him that his religion is a vain thing. You might as well go to the Witch of Endor for grace as to a priest; and if you rely upon words, the …

We have not treated the Latin Church after that fashion. There is not a hymn of real merit in the Latin which has not been translated, and in not a few cases oftener than once, with the result that the gems of Latin hymnody are the valued possession of the Christian Church in all English-speaking lands. One does not proceed far without making some discoveries which may account, to a certain extent, for the neglect of Greek hymnody by those men who are best qualified to pursue the study of it. The …

The Call of Moses
There is a great deal more room given in Scripture to the call of men to God's work than there is to their end. For instance, we don't know where Isaiah died, or how he died, but we know a great deal about the call God gave him, when he saw God on high and lifted up on His throne. I suppose that it is true to-day that hundreds of young men and women who are listening for a call and really want to know what their life's mission is, perhaps find it the greatest problem they ever had. Some don't …
