Today’s Scripture passage tells us, “And there are three that bear witness on earth: the Spirit, the water, and the blood; and these three agree as one” (1 John 5:8). It also says that the evidence, that witnesses the remission of our sins, is the gospel of the water and the Spirit.
There is concrete evidence that our Lord has delivered us from all our sins, granted us the eternal life, and adopted as His children. What is that evidence? The evidence of our salvation is three fold: the Holy Spirit, the water, and the blood. Those three elements become the evidence of our deliverance from all our sins. God delivered us from our sins by coming to this world in the human flesh, receiving the baptism, which transferred all our sins onto Jesus, and carrying those sins onto the Cross, where He bled to death, and resurrecting from the dead. The Apostle John is now teaching us the gospel Truth of the water and the Spirit.
