In the testimony of I John 5:6-9, Jesus Christ is revealed as He who came through water and blood, with the Spirit bearing witness to this truth. These three—Spirit, water, and blood—agree as one on earth, constantly testifying to the reality of His ministry, from His baptism to His sacrificial death, affirming that we have life because of Him.

In I John 5:6, it is declared that Jesus Christ came by water and blood, not only by water but by both, signifying the means through which He accomplished His mission. The water represents His baptism, marking the beginning of His ministry and His purpose to fulfill all righteousness. The blood signifies His violent death on the stake, the ultimate payment for the sins of the world, an act completed when He declared, "It is finished." Additionally, I John 5:8-9 states that there are three that bear witness on earth: the Spirit, the water, and the blood, and these three agree as one. Their witness converges upon the truth that Jesus Christ came in the flesh and that through Him, we have life. The Spirit continuously bears witness, affirming this truth as an ongoing testimony, because the Spirit is truth itself. The witness of God, testified through these three, is greater than the witness of men, confirming the divine testimony concerning His Son.
