Jesus Christ is the one who was baptized in water and died on the cross. He wasn't just baptized in water. He also died on the cross. The Holy Spirit has given a truthful witness about him. That's because the Spirit is the truth.

They are the Holy Spirit, the baptism of Jesus and his death. And the three of them agree.

We accept the witness of people. But the witness of God is more important because it is God who gives it. He has given witness about his Son.
10
Those who believe in the Son of God have accepted that witness in their hearts. Those who do not believe God's witness are calling him a liar. That's because they have not believed his witness about his Son.
11
Here is God's witness. He has given us eternal life. That life is found in his Son.
12
Those who belong to the Son have life. Those who do not belong to the Son of God do not have life.
