1 John 5:7-8

For there are three that testify: the Spirit, the water and the blood; and the three are in agreement.

(v7-8, NIV)

The Spirit testifies, but there are in fact three that testify. The Spirit, the water and the blood together testify. Now there are many false prophets and many different people saying many different things. Fortunately, the water, the blood and the Spirit are all in agreement. What do they testify about? They testify about Jesus!
