Charles Spurgeon Commentary 1 John 5:7-8

"And it is the Spirit that beareth witness, because the Spirit is the truth. For there are three who bear witness, the Spirit, and the water, and the blood: and the three agree in one." — 1 John 5:7-8 (ASV)

The Father, the Word, and the Holy Ghost: and these three are one. And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one (1 John 5:7–8).

Blessed is the man who has that threefold witness—the Spirit of God quickening him, the water cleansing his daily life, and the blood delivering his conscience from trouble, because he is delivered from sin by the atoning sacrifice of Christ.
