Psalm Chapter 91
"My God, in whom I trust" is the basis of faith. But being truly faithful means living according to the Word of God, not merely claiming to be one of God's children while doing nothing to genuinely obey Him. See A Life Of Faith.
"He who dwells in the shelter of the Most High, who abides in the shadow of the Almighty, will say to The Lord, "My refuge and my fortress [see Where Is It Safe?]; my God, in whom I Trust." For He will deliver you from the snare of the fowler and from the deadly pestilence; He will cover you with His pinions, and under His wings you will find refuge; His faithfulness is a shield and buckler. You will not fear the terror of the night, nor the arrow that flies by day, nor the pestilence that stalks in Darkness, nor the destruction that wastes at noonday. A thousand may fall at your side, ten thousand at your right hand; but it will not come near you. You will only look with your eyes and see the recompense of the wicked.
Because you have made The Lord your refuge, the Most High your habitation, no evil shall befall you, no scourge come near your tent. For He will give His angels charge of you to guard you in all your ways [see What Do Angels Do?]. On their hands they will bear you up, lest you dash your foot against a stone. You will tread on the lion and the adder, the young lion and the serpent you will trample under foot.
Because he cleaves to Me in love, I will deliver him; I will protect him, because he knows My Name. When he calls to Me, I will answer him; I will be with him in trouble, I will rescue him and honor him. With long life I will satisfy him [see When Will You Be Judged?], and show him my salvation." (Psalm 91:1-16 RSV)
Psalm Chapter 92
"A Song for the Sabbath" was composed to celebrate the only true God on His only true weekly Holy Day (see Sunday Is Not The Sabbath). The seventh-day Sabbath has been Christian, right from the beginning of Creation, because it was through and by means of Christ that the Creation happened (see Christ The Creator).
"A Psalm. A Song for the Sabbath.
It is good to give thanks to The Lord, to sing praises to Thy Name [see What Is God's Name?], O Most High; to declare Thy steadfast love in the morning, and Thy faithfulness by night, to the music of the lute and the harp, to the melody of the Lyre.
For Thou, O Lord, hast made me glad by Thy work; at the works of Thy hands I sing for joy. How great are Thy works, O Lord! Thy thoughts are very deep! The dull man cannot know, the stupid cannot understand this: that, though the wicked sprout like grass and all evildoers flourish, they are doomed to destruction for ever [see Why Does God Allow Evil?], but Thou, O Lord, art on high for ever.
For, lo, Thy enemies, O Lord, for, lo, Thy enemies shall perish; all evildoers shall be scattered [see Baptism Of Fire]. But Thou hast exalted my horn like that of the wild ox; Thou hast poured over me fresh oil. My eyes have seen the downfall of my enemies, my ears have heard the doom of my evil assailants.
The righteous flourish like The Palm Tree, and grow like a Cedar In Lebanon. They are planted in the house of The Lord, they flourish in the Courts of our God. They still bring forth fruit in old age, they are ever full of sap and green [see Good Fruit], to show that The Lord is upright [see The Lord's Plumb Line]; He is my rock, and there is no unrighteousness in Him." (Psalm 92:1-15 RSV)
Psalm Chapter 93
The purpose of the coming of The Messiah (see Israelite Monarchy - The Messiah) is to prepare the way for God's coming (see What Is Jesus Christ Doing Right Now? and The Throne Of God, From Heaven To Earth).
"The Lord reigns; He is robed in majesty; The Lord is robed, He is girded with strength. Yea, the world is established; it shall never be moved; Thy throne is established from of old [see The Ancient of Days]; Thou art from everlasting [see How Old Is God?].
The floods [see Hydrogen] have lifted up, O Lord, the floods have lifted up their voice, the floods lift up their roaring. Mightier than the Thunders of many waters, mightier than the waves of the sea, The Lord on high is mighty! Thy decrees are very sure; holiness befits Thy house, O Lord, for evermore." (Psalm 93:1-5 RSV)
