The Bible is moody, in a perfect way, and you need to know what sets off the mood swing. Sentences have moods. In the original language 1 Peter 1:3–12 is a single elephantine sentence. Some sentences really should run on. Clarity, brevity, and simplicity are virtues, but sometimes the subject is too grand to distill. Sometimes the matter really is that complex, deep, and wondrous. When we enter into salvation in all it’s fullness, I believe such run-on sentences of praise will be commonplace.
This whopping sentence is in the indicative mood. It indicates. It simply states the facts. But this is no stoic, “just the facts, ma’am.” This is good news. This is the gospel.
Following this hefty sentence are three lightweight ones in vv. 13–17. These sentences are in the imperative mood. They command. But the mood of this mood is still joyful.
When the Bible changes moods, you shouldn’t. For this to happen, it is essential that you see how the imperative and the indicative relate. A “therefore” lies between them. One mood produces the other, and it should always be the indicative first. The imperatives follow the indicative.
This is always the case for God’s people. Covenant, promise, and redemption came before Sinai. When God gave the law he prefaced it saying, “I am the Lord your God, who brought you out of the land of Egypt, out of the house of slavery. You shall have no other gods before me.” Here you have the same two kinds of sentences and the same “therefore” is implicitly understood to lie between them.
As the commands of God are planted in the soil of God’s grace, they are a tree of life. Try to plant them somewhere else, and you’ll only get poison apples.
Sinner, if your life has been nothing but one long stuttering incomplete imperative sentence, hear this gospel exclamation. What you cannot do, Christ did. He kept the law and bore the wrath of God for sinners so that all who trust in Him might have their sins removed and His righteousness imputed to them. If the Spirit takes that sentence deep into your soul and causes you to be born again, then you’ll find that your mood has changed, a mood that loves all the moods of the Scriptures.
