1 John 5:6-9

Jesus Christ is the One who was revealed as God’s Son by his water baptism and by the blood of his cross—not by water only, but by water and blood. And the Spirit, who is truth, confirms this with his testimony. So we have these three constant witnesses giving their evidence: the Spirit, the water, and the blood. And these three are in agreement. If we accept the testimony of men, how much more should we accept the more authoritative testimony of God that he has testified concerning his Son?
