This psalm makes no complaints or requests. It is all about praising and thanking God. We are observing David having a conversation with his soul. He is training his soul / his inner man to be grateful and to intentionally bless the Lord for His great and thorough care of everything.
Bless the Lord for His personal care of our lives - Psalm 103:1-6
Note the use of the words "my, me, you, your (thee/thy)." God is intimately involved with the details of your life. He thought of everything. He attends to everything and supplies for our physical, mental, emotional, and spiritual needs (Psalm 23:1-6; 37:3-7; 40:5; 139:1-24; Philippians 4:11-13, 19; I Thessalonians 5:16-24; I Peter 5:7, 10-11.
Bless the Lord for His world-wide care of His people and the nations - Psalm 103:6-19
Note the use of the words "all, us, those, man (mankind) and the reference to the nation Israel (Psalm 103:7). Our souls need to be trained to think outside of the realm of self and see the great needs of humanity. Millions of souls are organized into families, communities, nations, churches and other systems of belief and order. God is overseeing the flow of humanity. He is sovereignly and mercifully working among the nations (Psalm 104:1-35; 107:1-43; 113:1-9; 145:1-21; Proverbs 22:1; Acts 17:24-28; Romans 13:1; Daniel 4:34-35). "He's got the whole world in His hands!"
Bless the Lord for His universal care and rule of all things - Psalm 103:19-22
God is sovereign and attentive to the world that we can see. But His universe includes a world that we cannot see. It is a world inhabited by angelic and demonic beings. The angelic beings are willing servants of God Psalm 103:20-21; 104:1-4. Satan and his demons are rebellious to God. Yet they are limited and restrained in their actions. They face final defeat and ultimate judgement (Isaiah 14:12-17; Revelation 12:7-12). This portion of the psalm actually calls upon the angels of God to worship Him for His great and marvelous works. Men and angels should be and will be united to worship the Lord (Matthew 6:9-10; Revelation 4:1 - 5:14). See Psalm 113:4-6; 115:3; Daniel 4:34-35; Isaiah 45:20-23 cp. Philippians 2:5-11; Matthew 28:18.
Are you thankful for the life God has given you?
Are you attentive to His attentiveness?
- in your life?
- in the workings of the world?
- in the workings of the universe?
Are you at peace with God's sovereign grace and, mercy?
See Psalm 37:1-11; 63:3-7; 107:8; Jeremiah 9:23-24 cp. Luke 12:15-31; Lamentations 3:19-26; Romans 5:1-5; 8:28; Ephesians 3:14-21; Philippians 4:4-9; I Thessalonians 5:16-24; James 4:13-15; II Corinthians 12:7-10; Romans 11:33 - 12:3.
Consider Christ: He was at peace with the will of His Father. He patiently, submissively, and, in a very special way, joyfully endured the hardships of His life and ministry. His love and trust of the Heavenly Father, His love for us, and His dedication to the Scriptures made Jesus Christ the ultimate example of a servant of God. See John 6:38; 7:16-18; 13:1 cp. Hebrews 12:1-3; Matthew 26:45-46; I Peter 2:19-25; Mark 10:42-45; Galatians 2:20.
