1 (A Psalm of David.) Judge me, O Yahweh; for I have walked in mine integrity: I have trusted also in Yahweh; therefore I shall not slide.

2 Examine me, O Yahweh, and prove me; try my reins and my heart.

The study of the Apostolic writings has made us acquainted with the fact that the Psalms of David are the voice of the Spirit of God in him. ... Both Jesus and the apostles attribute the Psalms to inspiration; and David himself made the claim direct.

"The Spirit of God spake by me and His Word was on my tongue."

...This is where we must exercise discrimination. It was not merely to let us know what David thought or how Christ felt, but to give us a form of exercise by which we may both try and develop ourselves. They furnish to ourselves a test and a standard as to where we are in true spiritual life - a kind of mould into which we can fit ourselves to see if we correspond to the shape.

David was a man after God's own heart; Jesus was the Father's well-beloved Son.

Here in the Psalms, then, we have the sentiments and the forms of speech acceptable to God. Let us read them as if they were our own. Can we speak in their language? Can we utter their thoughts? Are we at home in their feelings and sentiments?

Here is where they are useful to us - not only informing us as to David's state of mind and his Greater Son, but giving a lesson in the etiquette of heaven, by which we may learn how acceptably to comport ourselves in our approaches to the majesty of heaven and earth, and how to walk before Him in our daily ways, so as to be well-pleasing to Him.

...while it is true that

"there liveth not a man upon earth that sinneth not,"

and that our hope is in the Lord's mercy, it is also true that that mercy is reserved for

"such as keep His covenant, and to those who remember His commandments to do them" 

(Psalm 103:18).

Bro Roberts - That we shall walk in integrity

3 For thy lovingkindness is before mine eyes: and I have walked in thy truth.

4 I have not sat with vain persons, neither will I go in with dissemblers.

5 I have hated the congregation of evil doers; and will not sit with the wicked.

6 I will wash mine hands in innocency: so will I compass thine altar, O Yahweh:

7 That I may publish with the voice of thanksgiving, and tell of all thy wondrous works.

8 Yahweh, I have loved the habitation of thy house, and the place where thine honour dwelleth.

9 Gather not my soul with sinners, nor my life with bloody men:

10 In whose hands is mischief, and their right hand is full of bribes.

11 But as for me, I will walk in mine integrity: redeem me, and be merciful unto me.

12 My foot standeth in an even place: in the congregations will I bless Yahweh.
