Read: Psalm 90:10, 16; Exodus 3:1, 7:7; 1 Corinthians 2:3 – 5; 2 Corinthians 4:7
Moses wrote Psalm 90– but when? Many commentators fix the writing during the wilderness wandering. But would a man over 100 years old write verse 10? Would a man who witnessed God’s miraculous deliverance of the Hebrews from Egypt write verse 16? Psalm 90 was likely written by Moses sometime after his 70th year, when he watched the flocks of his father-in-law Jethro on the backside of the desert, before his meeting with the Lord in the burning bush. He was thinking that his life was nearly over.
Think About It: Is it a reasonable expectation for a man almost 80 years old that most of his accomplishments are behind him? What do we know about Moses’ life before he was 80? What happened in Moses’ life after he was 80? Why might God have chosen an 80 year old (with help from an 83–year–old brother) to be the human instruments of deliverance for His people?
Prayer: Praise God that His ability to use me is not subject to the usual limitations.
Read: Psalm 90:1, 2, 4; 2 Peter 3:8 – 10; Isaiah 40:28 – 31
Moses reminded us in verses 1, 2, and 4 of Psalm 90 who God is: our eternal home, the eternal One. God has made us to have fellowship with Himself; unless we rest in Him, we will never be at rest. The eternal nature of God surpasses human comprehension. In the days before the flood men lived nearly one thousand years; but such a vast life span is but a day in God’s eyes. By the same token, in a single day, God can accomplish the work of a thousand years (or more!).
Think About It: What inference did Peter (2 Peter 3:9 – 10) and Isaiah (Isaiah 40: 28 – 31) draw from the concept of God’s elastic view of time? In other words, why is this a good thing for me?
Prayer: Thank God for His patience and His tireless power.
Read: Psalm 90:5, 6, 9b, 10; Romans 13:12; 1 Thessalonians 5:5 – 8
Very much in contrast to the eternal God, Moses showed us who man is in verses 5, 6, 9b, and 10 of Psalm 90. He compared man with the grass that grows up and fades in the heat of the day, and he reminded us of the brevity of the average life span. He also commented on our experiential knowledge of our brief life. We are carried away as by a flood, there is nothing we can do to resist the ever-flowing stream of time. We are also largely unaware of how swiftly our life passes away; we dream, perhaps thinking we have plenty of time, until death suddenly puts on end to our delusion.
Think About It: Moses wrote “we spend our years as a tale that is told.” How many chapters are in the story of my life, and how far along am I in that story? In what ways is life like sleep?
Prayer: Lord, help me to live life as one spiritually awake.
Read: Psalm 90:3, 7 – 9a, 11; Ephesians 2:2 – 3; Ecclesiastes 12:14; Revelation 20:11
In verses 3, 7 – 9a, and 11 of Psalm 90 Moses delineated man’s greatest problem: the wrath of God against man’s sin. This is not a comforting thought, and it is not meant to be.
Think About It: Apart from God’s grace, is there any way for a person to escape God’s wrath or to hide their sins from God?
Prayer: For strength to face the truth about myself in God’s presence.
Read: Psalm 90:12; Ecclesiastes 11:9, 12:1 – 14
Moses not only delineated truth about God and man in Psalm 90, he also wrote prescriptively in the light of those truths. In verse 12, he addressed man’s need in the light of temporality: to number our days and apply our hearts to wisdom.
Think About It: Am I ready to stand before the judgment seat of Christ? If God grants me the usual 70 to 80 years (or more), are my goals and plans consistent with the time I have remaining? Do I live with a sense of urgency?
Prayer: Teach me to number my days; grant me a heart of wisdom.
Read: Psalm 90:13 – 15; Ephesians 2:1 – 10; Psalm 32:2; Romans 4:7
In verses 13 – 15 of Psalm 90, Moses addressed our need, in the light of our sinfulness, to escape God’s wrath in judgment and experience His mercy.
Think About It: How could Hebrews in the Old Testament times be assured of experiencing God’s mercy? How can I be sure today that I experience God’s mercy?
Prayer: Praise God for His infinite mercy.
Read: Psalm 90:16 – 17; Psalm 49:11; 2 Corinthians 3:17 – 18; 1 Corinthians 3:11 – 15; Hebrews 13:15; Daniel 12:3
In verses 16 – 17 Moses addressed our need, in the light of our temporality and frailty, to reflect the beauty of the Lord and to have the work of our hands established by God.
Think About It: How do unbelievers seek to establish the works of their hands?
How can I be sure of doing something that will last for eternity?
Prayer: Help my life to count for eternity.
