Sensus plenior is a Latin phrase that means "fuller sense" or "fuller meaning". It is used in Biblical exegesis to describe the supposed deeper meaning intended by God but not by the human author. - Wikipedia
Sensus plenior is basically a hidden, deeper meaning. Perhaps an example might help us understand. Let's go to Matthew 1.
Matthew begins the chapter with the genealogy of Jesus. Then Joseph (the earthly father of Jesus) had a dream. In that dream, an angel of the Lord (quoting the prophet Isaiah), said this: “The virgin will conceive and give birth to a son, and they will call him Immanuel” (which means “God with us”). - Matthew 1:23
The angel in Joseph's dream used Isaiah's prophecy to talk about Jesus. But Isaiah spoke of a virgin giving birth 700 years before Jesus was born, preceeding the prophecy with this: "Therefore the Lord himself will give you a sign:" Isaiah's prophecy was from the Lord, about Himself."
Isaiah's prophecy had a deeper meaning than anyone would have expected. The hearer would have thought, "What? A virgin giving birth? That's crazy." But to Joseph, Isaiah's words were actually happening in his life, right then.
This sensus plenior stuff occurs a lot in the Bible. Here's another from the prophet Zechariah (6th century BC).
"Rejoice greatly, Daughter Zion! Shout, Daughter Jerusalem! See, your king comes to you, righteous and victorious, lowly and riding on a donkey, on a colt, the foal of a donkey." - Zechariah 9:9
Now, check THIS out.
"As they approached Jerusalem and came to Bethphage on the Mount of Olives, Jesus sent two disciples, ²saying to them, “Go to the village ahead of you, and at once you will find a donkey tied there, with her colt by her. Untie them and bring them to me. ³If anyone says anything to you, say that the Lord needs them, and he will send them right away.”
⁴This took place to fulfill what was spoken through the prophet:
⁵“Say to Daughter Zion, ‘See, your king comes to you, gentle and riding on a donkey, and on a colt, the foal of a donkey.’ ”
⁶The disciples went and did as Jesus had instructed them. ⁷They brought the donkey and the colt and placed their cloaks on them for Jesus to sit on." - Matthew 21:1-6
Jesus fulfilling prophecy 600 years after it was spoken. But in Zechariah's day, tge hearer would have thought, "What? A king coming on a donkey? Aren't kings usually carried on a litter?"
Matthew 24 is another example. Jesus and His disciples were talking about the stones in the city of Jerusalem. Jesus told them that one stone would not be left on another. That happened in 70 AD when the Romans destroyed the temple.
Then Jesus goes on to talk about "the abomination that causes desolation" in verse 15, referencing Daniel's prophecy.
A Greek ruler by the name of Antiochus IV desecrated the temple in Jerusalem. Antiochus called himself “Epiphanies” (“illustrious one” or “god manifest”). He set up an altar to Zeus over the altar of burnt offering, and he sacrificed a pig on the altar. But he did this BEFORE Jesus was born. Who was Jesus referring to then with His Daniel reference?
The Antichrist.
This prophecy has not been fulfilled yet. And there's the perfect example of sensus plenior. A deeper meaning.
The Bible is an amazing thing to explore and study. The deeper one digs into it, the more amazing it becomes.
