“Praise ye the LORD. Praise God in His sanctuary: praise Him in the firmament of His power.” Psalm 150:1 (KJV)
One thing a Christian can learn from reading the Psalms, and especially those that express “Praise ye the LORD”; is that we are to “Praise the LORD”.
It does not matter the time, the place, life’s situation or circumstances; the child of God is to praise the LORD. Why? Because He is worthy. That is reason enough.
Let me have Charles H. Spurgeon give you his words concerning Psalm 150:1;
“Praise ye the Lord.” Hallelujah! The exhortation is to all things in earth or in heaven. Should they not all declare the glory of him for whose glory they are, and were created? Jehovah, the one God, should be the one object of adoration. To give the least particle of his honour to another is shameful treason; to refuse to render it to him is heartless robbery. “Praise God in his sanctuary.” Praise El, or the strong one, in his holy place. See how power is mentioned with holiness in this change of names. Praise begins at home. “In God’s own house pronounce his praise.” The holy place should be filled with praise, even as of old the high-priest filled the sanctum sanctorum with the smoke of sweet-smelling incense. In his church below and in his courts above hallelujahs should be continually presented. In the person of Jesus God finds a holy dwelling or sanctuary, and there he is greatly to be praised. He may also be said to dwell in holiness, for all his ways are right and good; for this we ought to extol him with heart and with voice. Whenever we assemble for holy purposes our main work should be to present praises unto the Lord our God. “Praise him in the firmament of his power.” It is a blessed thing that in our God holiness and power are united. Power without righteousness would be oppression, and righteousness without power would be too weak for usefulness; but put the two together in an infinite degree and we have God. What an expanse we have in the boundless firmament of divine power! Let it all be filled with praise. Let the heavens, so great and strong, echo with the praise of the thrice holy Jehovah, while the sanctuaries of earth magnify the Almighty One.
from the TREASURY OF DAVID, e-Sword edition
We ought always Praise the LORD; for He is worthy of praise, worship, and adoration.
