Verses 7 and 8 describe thousands falling on either side of those who trust God, noting, "You will only observe with your eyes and see the punishment of the wicked.” This interprets the death of the thousands as God's punishment for sin and places the deliverance of God's people in that context. In other words, it is not a promise that those who trust God will never die of disease or even in some military conflict, but that they will not suffer those or any other calamities as God's judgment against them for their sin. Their sin has been atoned for by the blood of Jesus Christ.

As we noted in yesterday’s reading, the psalm's promises are for you only if the God of the Bible is your God. And what promises they are! There are four metaphors for the security we can have in God. God will be our "shelter” and "shadow” (v. 1) and our "refuge" and "fortress" (v. 2). There are also four names for God, which give substance and strength to the metaphors. He is "the Most High,” “the Almighty" (v. 1), "the LORD” and "my God" (v. 2). When the psalmist identifies God as his God in the last expression, it is a way of saying that the shelter, shadow, refuge and fortress are for those who really do dwell in God and trust him.

All the psalms are from God and are wonderful in their several ways. But there are some that have commended themselves to God's people as being especially rich and comforting, and to which they have repeatedly turned in times of sickness, loneliness and trouble. Psalm 91 is one of these special psalms. It has been committed to heart by thousands of people, and millions have turned to it with thankfulness in the midst of life's calamities.

Don't you want God to do that? Don't you want your life here and what you do here to have meaning? Don't you want to be a blessing to others? I am sure you do. But I remind you that the only way that can happen is if God establishes your work. May he do that so that others who come after you will be blessed because of you, and so, when you die and appear before God the Father, you will hear him say, "Well done, good and faithful servant! You have been faithful with a few things; I will put you in charge of many things. Come and share your master's happiness” (Matt. 25:21, 23)!

The third section of Psalm 90 (vv. 7-12) recognizes that man's greatest problem is not just his frailty, that is, that he exists for only a short bit of time and is then no more. It is that he is also a sinner and is subject to the just wrath of God. In fact, it is sin that is the cause of his death and misery. Moses must have been thinking of the fall of Adam and Eve when he wrote this (remembering that he also wrote Genesis 3), as well as of his own sin in striking the rock and of God's judgment which kept him from the promised land.
