When someone has done well at an assigned task or has displayed a remarkable Christian quality, he deserves praise. If that is true of humans, how much more do we have reason to praise Jehovah God! We can praise him because of his immense power, as seen in the wonders of his creation, or because of his warm dealings with humankind, as evidenced by his provision of the ransom sacrifice of his own Son. The writer of the 147th Psalm was moved to praise Jehovah. He also encouraged others to join him in giving God praise. (Ps. 147:7, 12) We do not know who wrote this psalm, but the psalmist apparently lived about the time when Jehovah restored the Israelites to Jerusalem from Babylonian exile. (Ps. 147:2) The restoration of God’s people to their place of true worship would certainly have moved the psalmist to praise Jehovah. What reasons do you have to cry out “Hallelujah!” in your own life?​—Ps. 147:1, ftn. w17.07 17 ¶1-3
