(This reading is based on Psalm 103, read in accordance with the Revived by His Word initiative of the General Conference of Seventh-day Adventists.)
"Bless the Lord O my soul, and all that is within me, bless His holy name." Ps 103: 1
In the first four (4) Commandments of the ten (10) listed in Exodus 20 God is quite articulate about His desire for our worship. In fact, He's downright jealous for it (Ex. 20: 5). And yet He's not arrogant about it - albeit that He made us. Bearing in mind that "All scripture is given by inspiration of God," we see Him through David in Psalm 103 providing a litany of reasons why He deserves our praise; reasons that are not just cosmic, but as personal as we could require them to be. Here are some excellent reasons to worship, yeah "bless" the Lord:
Verse 3 - Iniquities forgiven; Diseases healed
Verse 4 - Redemption from destruction; Crowned (Treated) with lovingkindness and tender mercies
Verse 5 - Satiated with good thing; sustained as an eagle
Verse 6 - Executes righteous judgement on behalf of the oppressed.
Verse 8 - Merciful, gracious, and slow to anger
Verses 10-13 - Pitied us as a forgiving father; seeking to remove our transgressions from us instead of punishing us as we deserve.
Verses 19-22 - Incidentally, He's not just a private, personal God; "His throne is prepared in the heavens, and His kingdom rules over all." He's the God of angels; powerful armies of angels! And on a whole other level (outside of the singular fact of His creatorship), He's the God of whomever chooses to do His pleasure - to such He's able to treat with the full spectrum of His salvific virtues.
