According to the context of 1 John 5, it seems like talking about the testimony of God - that Lord Jesus Christ is the Son of God, that God has given us eternal life, and this life is in his Son. :-
7 For there are three that testify:
8 the Spirit, the water and the blood; and the three are in agreement.
5:7 並且有聖靈作見證，因為聖靈就是真理。
5:8 作見證的原來有三，就是聖靈，水，與血。這三樣也都歸於一。
1 John 5:7-8
Lord Jesus, who is "the Word became flesh" admitted that he is Christ:
61 But Jesus remained silent and gave no answer. Again the high priest asked him, "Are you the Christ, the Son of the Blessed One?"
62 "I am," said Jesus. "And you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven."
Mark 14:61-62
The one from heaven also testifies - Matthew 馬 太 福 音 3:16

1:13 你們既聽見真理的道，就是那叫你們得救的福音，也信了基督，既然信他，就受了所應許的聖靈為印記。
Ephesians 以 弗 所 書 1:13
30 And do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption.
4:30 不要叫神的聖靈擔憂。你們原是受了他的印記，等候得贖的日子來到。
Ephesians 以 弗 所 書 4:30
(5 Your attitude should be the same as that of Christ Jesus: )
6 Who, being in very nature God, did not consider equality with God something to be grasped,
7 but made himself nothing, taking the very nature of a servant, being made in human likeness.
8 And being found in appearance as a man, he humbled himself and became obedient to death-- even death on a cross!
9 Therefore God exalted him to the highest place and gave him the name that is above every name,
10 that at the name of Jesus every knee should bow, in heaven and on earth and under the earth,
11 and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.
(“你們當以基督耶穌的心為心。) 他本有神的形像, 不以自己與神同等為強奪的，反倒虛己, 取了奴僕的形像, 成為人的樣式。既有人的樣子, 就自己卑微, 存心順服, 以至於死, 且死在十字架上。所以神將他升為至高，又賜給他那超乎萬名之上的名，
2:10 叫一切在天上的，地上的，和地底下的，因耶穌的名，無不屈膝，（腓利比書 2:5－10）”
16 "I, Jesus, have sent my angel to give you this testimony for the churches. I am the Root and the Offspring of David, and the bright Morning Star."
22:16 我，耶穌差遣我的使者為眾教會將這些事向你們證明。我是大衛的根，又是他的後裔。我是明亮的晨星。

22:17 聖靈。。。說 來。。。。
Revelation 啟 示 錄 22:17
20 He who testifies to these things says, "Yes, I am coming soon." Amen. Come, Lord Jesus.
22:20 證明這事的說，是了。我必快來。阿們。主耶穌阿，我願你來。
Revelation 啟 示 錄 22:20
16 As soon as Jesus was baptized, he went up out of the water. At that moment heaven was opened, and he saw the Spirit of God descending like a dove and lighting on him.
17 And a voice from heaven said, "This is my Son, whom I love; with him I am well pleased."
3:16 耶穌受了洗，隨既從水裡上來。天忽然為他開了，就看見神的靈，彷佛鴿子降下，落在他身上。
3:17 從天上有聲音說，這是我的愛子，我所喜悅的。
Matthew 馬 太 福 音 3:16
39 Acknowledge and take to heart this day that the LORD is God in heaven above and on the earth below. There is no other.
4:39 所以，今日你要知道，也要記在心上，天上地下惟有耶和華他是神，除他以外，再無別神。
