Jesus prepared His disciples to spread His truth by telling them as much as they could handle, as much as the spoken word can communicate to an open mind. However, He wanted to tell them more, as He said: “I have much more to say to you, more than you can now bear” (John 16:12). Jesus then promised: “But when he, the Spirit of truth, comes, he will guide you into all truth” (verse 13, emphasis added).
Again, reading the Bible or listening to sermons isn’t enough. Complete truth only comes from a personal relationship with the Holy Spirit, for the Holy Spirit speaks to us at a level far beyond the reach of reading, listening, human vocabulary, and human reasoning. And as Jesus also said:
“When the Helper comes, whom I will send to you from the Father, namely, the Spirit of truth who comes from the Father, He will testify about Me.” (John 15:26 NASB)
In the movie A Few Good Men, there’s a climactic moment near the end of the court martial scene. In response to Tom Cruise’s character demanding, “I want the truth!” Jack Nicholson’s character shouts, “YOU CAN’T HANDLE THE TRUTH!” Without the help of the Holy Spirit, we can’t handle the truth. It’s scope and meaning won’t be fully grasped by our limited minds. Yet the Spirit of truth will open our minds to the truth:
“It is the Spirit who testifies, because the Spirit is the truth.” (1 John 5:6 NASB)
