In our psalms and in our prayers we often indicate the real elements of religion as fully, and perhaps as clearly, as in our exhortations. In this psalm of David we have the essential principles of piety.

I. MINDFULNESS OF GOD'S POWER AND GOODNESS. (Vers. 8, 9, 12.) We cannot feel toward him as we should except we consider "his deeds among the people," except we "talk of all his wondrous works," except we "remember his marvellous works." Calling these to mind, we shall be powerfully and rightly affected by a realization of his Divine power and goodness. We shall naturally dwell on his works in nature, his power as displayed in the creation and sustenance of our own spirit and our own human life, his handiwork in the providential ordering of the world.

II. A SENSE OF HIS INTIMATE DIVINE RELATION TO US AND TO THE WHOLE WORLD. (Vers. 13, 14.) As the children of Israel felt that they were chosen of God, having received direct and special communication and consideration; as they could speak of themselves as his "chosen ones," and could say, "He is the Lord our God;" so we may and must feel that we all are the objects of his Divine regard, that he looks with benignant eye on us and stretches out the hand of Divine friendship toward us, that he is the Lord our God who has chosen us and whom we have chosen. And as they were taught to feel that "his judgments are in all the earth," so we also are to think of him as the supreme almighty Power reigning and ruling everywhere, "speaking and it is done, commanding and it stands fast" (Psalm 33:9).

III. THANKSGIVING IN MEMORY OF HIS GOODNESS AND MERCY. (Vers. 8, 9.) A large part of the sacred service of the Jews consisted in praise. In heathendom there was much of deprecation, something of supplication, little or nothing of praise. God's own people had such a sense of his absolute excellence that they "gave thanks at the remembrance of his holiness," and such a remembrance of his distinguishing goodness to them that they sang psalms of praise because they were such large recipients at his hand. The piety of the Hebrew was vocal with constantly recurring praise; the psalms of the "sweet singer of Israel," and of Jewish worship altogether, were so largely hymns of thanksgiving, that we always associate the thought of praise with the name of them. And from us, for whom as for them God has done such great things, for whom, indeed, God has done greater things than for them, it may well be that praise is found to be the prevailing note of our worship, the chief strain in our piety.

IV. JOY IN GOD. (Ver. 10.) The people were encouraged to "glory in God's holy Name," to triumph in the thought that they were worshipping him who was the "Holy One of Israel," in every way worthy of their profoundest adoration; also to "rejoice" in him as in One the knowledge and service of whom was the spring of truest and abiding satisfaction. We may well do the same; and having "such an High Priest" as we have, such a Saviour and Divine Friend, such a Refuge of our soul, we may glory and rejoice with intenser joy than they.

V. COMMUNION WITH GOD. (Ver. 11.) We do not enter into the full heritage of the people of God until we "seek the face of the Lord continually." Both in his house and in our own home, we are to seek him, to "seek his strength," to come consciously into his presence, to draw nigh with our spirit to his Spirit, to walk with him, to hold converse with him, to pour out our heart before him, to dwell in the house of the Lord for ever, beholding his beauty as well as inquiring in his temple (Psalm 27:4). - C.

I. THE SUBJECT HERE SUGGESTED FOR OUR COMMONPLACE TALK: "HIS WONDROUS WORKS." We ought to talk more about God's wondrous works.

1. As we find them in Holy Scripture.

2. As we find them in the history of our own country.

3. As we find them in our own individual history.

II. THE EXCELLENCY OF THIS SUBJECT IS BOTH NEGATIVE AND POSITIVE.

1. Negative. Were we to talk more of God's wondrous works —

(1)We should talk less about our own works.

(2)We should be free from talking of other people's works.

(3)It would keep us from the ordinary frivolities of conversation.

2. Positive. The habit once acquired of talking more of God's wondrous works —

(1)Would necessitate stricter habits of observation and of discrimination in watching the providence of God;

(2)would be very ennobling;

(3)would cause our gratitude to glow and would give an impulse to our entire life.

III. LET ME URGE THIS TAKING ORDINARILY AND COMMONLY ABOUT GOD'S WONDROUS WORKS. Not only will it prevent much evil and do us much good, but it will be the means of doing much good to others. It will —

1. Impress the sinner.

2. Enlighten the ignorant.

3. Comfort the desponding.

( C. H. Spurgeon.)
