Blessed are they that Mourn
Blessed are they that mourn. Matthew 5:4 Here are eight steps leading to true blessedness. They may be compared to Jacob's Ladder, the top whereof reached to heaven. We have already gone over one step, and now let us proceed to the second: Blessed are they that mourn'. We must go through the valley of tears to paradise. Mourning were a sad and unpleasant subject to treat on, were it not that it has blessedness going before, and comfort coming after. Mourning is put here for repentance. It implies …

No Sorrow Like Messiah's Sorrow
Is it nothing to you, all you who pass by? Behold, and see, if there be any sorrow like unto my sorrow! A lthough the Scriptures of the Old Testament, the law of Moses, the Psalms, and the Prophecies (Luke 24:44) , bear an harmonious testimony to MESSIAH ; it is not necessary to suppose that every single passage has an immediate and direct relation to Him. A method of exposition has frequently obtained [frequently been in vogue], of a fanciful and allegorical cast [contrivance], under the pretext …

Exhortations to Christians as they are Children of God
1 There is a bill of indictment against those who declare to the world they are not the children of God: all profane persons. These have damnation written upon their forehead. Scoffers at religion. It were blasphemy to call these the children of God. Will a true child jeer at his Father's picture? Drunkards, who drown reason and stupefy conscience. These declare their sin as Sodom. They are children indeed, but cursed children' (2 Peter 2:14). 2 Exhortation, which consists of two branches. (i) Let …

Repentance
Then has God also to the Gentiles granted repentance unto life.' Acts 11: 18. Repentance seems to be a bitter pill to take, but it is to purge out the bad humour of sin. By some Antinomian spirits it is cried down as a legal doctrine; but Christ himself preached it. From that time Jesus began to preach, and to say, Repent,' &c. Matt 4: 17. In his last farewell, when he was ascending to heaven, he commanded that Repentance should be preached in his name.' Luke 24: 47. Repentance is a pure gospel grace. …

Samuel
Alike from the literary and the historical point of view, the book[1] of Samuel stands midway between the book of Judges and the book of Kings. As we have already seen, the Deuteronomic book of Judges in all probability ran into Samuel and ended in ch. xii.; while the story of David, begun in Samuel, embraces the first two chapters of the first book of Kings. The book of Samuel is not very happily named, as much of it is devoted to Saul and the greater part to David; yet it is not altogether inappropriate, …
