This Psalm was requested by Brother Roberts to be read at his funeral, and is so meaningful in such a circumstance. It was probably written when the ark was brought to Jerusalem with great rejoicing (1Chr. 16).

The Psalm is a Song of pure and joyous worship; there is not a single petition contained in it. It is like a stream of grateful praise, whose gentle and regular words rise higher and higher as it flows from a mind moved to the innermost depths by blessings received. So the Song presents a self-exhortation to bless Yahweh for His benefits. GEM

1 (A Psalm of David.)

Bless Yahweh, O my soul: and all that is within me, bless his holy name.

2 Bless Yahweh, O my soul, and forget not all his benefits:

We have at least a hundred reasons for being thankful where we have but one for being sad and melancholy.‭ ‬Why,‭ ‬then,‭ ‬are we more prone to the latter than the former‭? ‬Is it because we forget‭?

TC March 1898

12 As far as the east is from the west, so far hath he removed our transgressions from us.

East and West also relates to the conquest of sin - morally in Gethsemane and physically at Golgotha - each within sight of the Holy of Holies - the way to which was opened thereby.:hence Psa.103:12 As far as the east is from the west, so far hath he removed our transgressions from us. 

Bro Paul Hart

18 To such as keep his covenant, and to those that remember his commandments to do them.

We have a tremendous, overwhelming -- almost crushing -- responsibility to God. We should be conscious of it every moment. He has richly given us everything: life and existence and consciousness; the revelation of Himself and His loving goodness; His Word; His Purpose; His call to eternal communion with Him in the Divine Nature; the dreadful sacrifice of His only-begotten Son for our salvation; an earth-home full of infinite beauty and divine imprint; the incomparably marvelous tools of the human mind and hands; the power of thought and memory and imagination.

And we have agreed to accept all this from Him, on His conditions. And He asks so little in comparison in return, and that for our own good -- simply the casting off of everything to do with this dark, dying, sinful world and its follies, and total love and devotion and service to Him. And yet we putter away our life in the stinking rubbish heap of the present, as though all these glorious things never existed. Let us open our eyes and hearts, before it has all passed away beyond our grasp for ever. Opportunity pauses for us just so long: and then -- eternal darkness.
