1 John 5:6c

This is the one who came by water and blood—Jesus Christ. He did not come by water only, but by water and blood. And it is the Spirit who testifies, because the Spirit is the truth.

(v6, NIV)

At the end of verse 6, John focuses in on the Spirit. The Spirit testifies. The reason the Spirit testifies is because the Spirit is the truth. How does the testimony of the Spirit tie in with this passage? Well, if we look ahead, we'll realize that John begins to talk about testimonies in the next section. He talks about the testimony of God and the testimony of man.

So the Spirit testifies and the Spirit is the truth. There are actually many different things or spirits that testify about many different things. There are all sorts of teachings or sayings or proclamations. Looking back to chapter 4, John talks about testing the spirits. We need to test the spirits to see whether they are from God. The problem is that there are many false prophets. These false prophets are testifying about false things. However, the Spirit is the truth and we need to learn how to distinguish between the Spirit of truth and the spirit of falsehood.
