It is very interesting to me that God in trinity testifies to the way of salvation. I’d never really thought about that before. John tell us,
This is the one who came by water and blood — Jesus Christ. He did not come by water only, but by water and blood. And it is the Spirit who testifies, because the Spirit is the truth. For there are three that testify: the Spirit, the water and the blood; and the three are in agreement. (6-8)
I think for most people reading this, John’s words can be confusing because they don’t know the background. But there were people in John’s day that said that Jesus wasn’t always the Christ. Instead, they had this weird teaching that “the Christ” descended as a spirit on Jesus at his baptism, but departed at his death.
So according to them, Jesus wasn’t the “Christ” when he died and thus he didn’t truly pay for our sins.
But the truth is Jesus proved himself to be the Christ at his baptism and death. At his baptism, the Father expressed his approval of him and the Holy Spirit descended on him like a dove. Then at the cross, he paid the price for our sins, just as the scriptures predicted that he would.
So we have Father, Son, and Spirit all testifying to the way of salvation, and that is through Jesus the Messiah.
Why is this important? Because if God says something, there’s no room for argument. And that’s what John tells us in verses 9-10.
We accept man’s testimony, but God’s testimony is greater because it is the testimony of God, which he has given about his Son. Anyone who believes in the Son of God has this testimony in his heart. Anyone who does not believe God has made him out to be a liar, because he has not believed the testimony God has given about his Son. (9-10)
In short, we often believe people’s testimony. How can we not believe God when he speaks?
And now because God has spoken, we cannot reject God’s testimony and still claim to be following God.
What is God’s testimony? John tells us in verses 11-12.
And this is the testimony: God has given us eternal life, and this life is in his Son. He who has the Son has life; he who does not have the Son of God does not have life. (11-12)
Many people, however, don’t like this testimony. They want to believe there are many ways to God besides Jesus. But John tells us that for us to say that is to call God a liar.
But if we will only believe it, we can peace and confidence concerning our salvation. Why? Because our salvation is not based on anything that we do. It’s based solely on the grace of God and the work Jesus did on the cross for us. All we have to do is to accept it.
In John’s words,
I write these things to you who believe in the name of the Son of God so that you may know that you have eternal life. (13)
Note that John wrote not that you might think you have eternal life, but that you would know it in your heart.
How about you? Have you accepted the testimony of God? Do you know that you have eternal life?
