Psalm 145 The Greatness Of The LORD.
God is not a theological topic only, He acts in history, and as sovereign ruler over all, He reigns as King. We praise Him for who and what He is and does (v. 1). It is a daily act of praise, but it lasts for all eternity (v. 2). “Great is the LORD, and greatly to be praised; and His greatness is unsearchable.” (v. 3) The greatness of the LORD can not be exhausted, nor is His power and understanding, nor the marvellous things He has done and continues to do (Cf. Job 5:9; 9:10; 11:7; Ps. 147:5; Is. 40:28). However, it does not mean that either He or His truth are incomprehensible to us, as some suppose. God has given us His word precisely because He and His word are comprehensible to us, though our knowledge is not as exhaustive as His. “Oh the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments and His ways past finding out!” (Rom. 11:33)
The history of the LORD’s works are passed from generation to generation (v. 4 Cf. Is. 38:19). His glorious splendour and majesty, as well as His works, are both the subject of our meditation (v. 5). What He has done and who He is will be declared and remembered by all peoples (vv. 6-7). “The LORD is gracious and full of compassion, slow to anger and great in mercy.” (v. 8 Cf. Ps. 86:5, 15) Grace and mercy is always there for those who turn from their sin to Him (Cf. Ex. 34:6-7). The LORD does not “clear” the guilty, He pardons them through the payment of another (Cf. Nu. 14:18). As the apostles also bear witness, the longsuffering of the Lord, which stems from His goodness, is for repentance and salvation (Cf. Rom. 2:4; II Pet. 3:15). The LORD is also good to all, in that “His tender mercies are over all His works.” (v. 9)
These same works give Him praise, and the saints bless the LORD (vv. 10, 21 Cf. Ps. 19:1). We also speak of what we know. The works and saints of the LORD speak of the glory and majesty of His everlasting kingdom, His power, and a dominion that “endures throughout all generations.” (vv. 11-13 Cf. Ps. 100:5; Jer. 33:11; Dan. 2:44; 4:3; Na. 1:7) He lifts up the fallen and humbled (v. 14 Cf. Ps. 146:8). The same works that give Him praise, also look to Him for their food in season (vv. 15-16 Cf. Pss. 104:21, 27-28; 136:25). “The LORD is righteous in all His ways, gracious in all His works.” (v. 17) When our prayers are true, and we approach in fear or due respect, the LORD draws near and saves us (vv. 18-19). He also preserves us to the end, “but all the wicked He will destroy.” (v. 20) So a certain judgment will come, but the saints will persevere.
