The Gospel of Mark testifies that Jesus Christ is the Son of God and God Himself. And it also testifies that He is our Savior. So we can see the writer of the Gospel of Mark bearing witness of Jesus forcefully, testifying that He is God Himself and our Savior. That's why I would like to bear witness of this Jesus Christ manifested in the Gospel of Mark as much as possible, based on the gospel of the water and the Spirit. What is obvious is that the core Truth of Christianity is found in the gospel of the water and the Spirit. Jesus said to Nicodemus, "Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God" (John 3:5). Where, then, is the gospel Truth of the water and the Spirit revealed? This Truth of salvation is revealed in detail in the ministry of Jesus and the ministry of John the Baptist, the substance of the gospel of the water and the Spirit. Faith in the gospel of the water and the Spirit exerts a tremendous influence on other people's souls. The faith of this gospel enables every believer to come before the holy God, come under the guidance of the Holy Spirit, and have a personal relationship with Jesus Christ. Such faith allows us to attain "spiritual priesthood." We must preach that Jesus Christ is our Savior according to the revelation of the gospel of the water and the Spirit and our faith. So, we do not want the gospel of the water and the Spirit to remain exclusively ours. This gospel of the water and the Spirit is the gospel that should be shared with everyone all over the world.
