The mighty God, even the Lord, hath spoken - Here the essential names of God are used: אל אלהים יהוה El, Elohim, Yehovah, hath spoken. The six first verses of this Psalm seem to contain a description of the great judgment: to any minor consideration or fact it seems impossible, with any propriety, to restrain them. In this light I shall consider this part of the Psalm, and show: -

First, The preparatives to the coming of the great Judge. El Elohim Jehovah hath spoken, and called the earth - all the children of men from the rising of the sun unto the going down thereof. Out of Zion, the perfection of beauty, (מכלל יפי michlal yophi, the beauty where all perfection is comprised), God hath shined, Psalm 50:1, Psalm 50:2.

1. He has sent his Spirit to convince men of sin, righteousness, and judgment.

2. He has sent his Word; has made a revelation of himself; and has declared both his law and his Gospel to mankind: "Out of Zion, the perfection of beauty, God hath shined," Psalm 50:2. For out of Zion the law was to go forth, and the word of the Lord from Jerusalem. Isaiah 2:3.

Secondly, The accompaniments.

1. His approach is proclaimed, Psalm 50:3 : "Our God shall come."

2. The trumpet proclaims his approach: "He shall not keep silence."

3. Universal nature shall be shaken, and the earth and its works be burnt up: "A fire shall devour before him and it shall be very tempestuous round about him," Psalm 50:3.

Thirdly, The witnesses are summoned and collected, and collected from all quarters; some from heaven, and some from earth.

1. Guardian angels.

2. Human associates: "He shall call to the heavens from above, and to the earth, that he may judge his people," Psalm 50:4.

Fourthly, The procedure. As far as it respects the righteous, orders are issued: "Gather my saints," those who are saved from their sins and made holy, "together unto me." And that the word saints might not be misunderstood it is explained by "those that have made a covenant with me by sacrifice;" those who have entered into union with God, through the sacrificial offering of the Lord Jesus Christ. All the rest are passed over in silence. We are told who they are that shall enter into the joy of their Lord, viz., only the saints, those who have made a covenant with God by sacrifice. All, therefore, who do not answer this description are excluded from glory.

Fifthly, The final issue: all the angelic hosts and all the redeemed of the Lord, join in applauding acclamation at the decision of the Supreme Judge. The heavens (for the earth is no more, it is burnt up) shall declare his righteousness, the exact justice of the whole procedure, where justice alone has been done without partiality, and without severity, nor could it be otherwise, for God is Judge himself. Thus the assembly is dissolved; the righteous are received into everlasting glory, and the wicked turned into hell, with all those who forget God. Some think that the sentence against the wicked is that which is contained, Psalm 50:16-22. See the analysis at the end, and particularly on the six first verses, in which a somewhat different view of the subject is taken.

Why all Things Work for Good
1. The grand reason why all things work for good, is the near and dear interest which God has in His people. The Lord has made a covenant with them. "They shall be my people, and I will be their God" (Jer. xxxii. 38). By virtue of this compact, all things do, and must work, for good to them. "I am God, even thy God" (Psalm l. 7). This word, Thy God,' is the sweetest word in the Bible, it implies the best relations; and it is impossible there should be these relations between God and His people, and …

Epistle cxxi. To Leander, Bishop of Hispalis (Seville).
To Leander, Bishop of Hispalis (Seville). Gregory to Leander, Bishop of Spain. I have the epistle of thy Holiness, written with the pen of charity alone. For what the tongue transferred to the paper had got its tincture from the heart. Good and wise men were present when it was read, and at once their bowels were stirred with emotion. Everyone began to seize thee in his heart with the hand of love, for that in that epistle the sweetness of thy disposition was not to be heard, but seen. All severally …

The Third Commandment
Thou shalt not take the name of the Lord thy God in vain: For the Lord will not hold him guiltless that taketh his name in vain.' Exod 20: 7. This commandment has two parts: 1. A negative expressed, that we must not take God's name in vain; that is, cast any reflections and dishonour on his name. 2. An affirmative implied. That we should take care to reverence and honour his name. Of this latter I shall speak more fully, under the first petition in the Lord's Prayer, Hallowed be thy name.' I shall …
