Psalms 146-150 constitute the final doxology of the Psalter, beginning with a rousing call to praise the Lord (146:1). Psalm 146 emphasizes the protection which the Lord provides for those who cannot help themselves- the oppressed (v. 7a); the hungry (v. 7b); the prisoners (v. 7c); the blind (v. 8a); those who are bowed down (v. 8b); the righteous (v. 8c); the sojourners (v. 9a); the widow and fatherless (v. 9a). Those who are despised by the world are the favorites of the Lord. And only He can afford protection against the church’s enemies since human protectors are weak and subject to death (v. 3). The Lord, however, is the omnipotent and gracious protector who created all things (v. 6). The biblical logic of the Psalmist is that if God exercised his infinite power in the creation of the world, surely he exercises his power in the preservation of the world, but in particular, the people of God. The doctrines of creation and providence provide rich food for the helpless believer in need of divine protection. Question and answer 28 of the Heidelberg Catechism beautifully illustrates this truth. The Catechism asks:
Q: What advantage is it to us to know that God has created, and by his providence does still uphold all things? Answer: That we may be patient in adversity; (a) thankful in prosperity; (b) and that in all things, which may hereafter befall us, we place our firm trust in our faithful God and Father, (c) that nothing shall separate us from his love; (d) since all creatures are so in his hand, that without his will they cannot so much as move.
Dear believer, if you are united to Jesus Christ, his almighty resurrection power- that power which created and sustains this world- ceaselessly exerts itself on your behalf, protecting and preserving you from all your enemies so that apart from God’s gracious and powerful hand, you cannot so much as move. That power, the power “that enables him to bring everything under his control” (Phil. 3:21) will one day manifest itself in the eternal reign of the Triune God in a new creation where righteousness dwells: “The Lord will reign forever, your God, O Zion, to all generations. Praise the Lord!” (v. 10).
