The Lord will keep you from all evil; He will keep your soul." —Psalms 121:7
Psalm 121 is a song for pilgrims on their way to the City of God, a journey through mountain passes and perilous places, ambush sites, bandits and brigands all around. Pilgrims need protection! Thus, "keeping" is the theme of this psalm.
The centerpiece of the psalm is verse seven: "The Lord will keep you from all evil; He will keep your soul." The parallelism establishes the only protection God has promised. He has not said that he will keep me from danger in the coming years but He has promised that He will keep my soul—the part of me that I call "myself," the "me" that is timeless and eternal. As Jesus said with such fine irony (and humor, I suspect): "Some of you will be put to death... But not a hair of your head will perish" (Luke 21:16).
The psalm is very personal. (The pronouns "you" and "your" are singular throughout.) "Hey, YOU," the poet says, "I'm speaking to you. You, the one listening to this song. Hear this: 'The Lord will keep your going out and your coming in from this time forth, and forevermore'" (119:8).
"Forevermore" is just that: From here to eternity. "He is able to keep you from stumbling, and to present you faultless, before the presence of His glory with exceeding joy" (Jude 25).
