The apostle John uniquely records the testimony of Jesus Christ's blood as a witness to His identity and purpose. Jesus allowed His blood to be spilled as the price to purchase the church of God, redeeming the firstfruits of His creation. This blood, witnessed by John as it poured out, serves as a silent testimony to Christ's sacrifice and divine mission. Just as the presence of the Holy Spirit testifies without spoken words, the spilling of Christ's blood onto the ground made a profound witness to John. Furthermore, Christ's blood covers our sins, allowing us to appear before the Father, justified and washed clean, mirroring the process through which we receive God's Spirit. These three witnesses—water, blood, and Spirit—identified not only the firstborn Son of God but also apply to all the sons of God, marking significant steps in our journey to know God.
