I John 5:6-8
And it is the Spirit who bears witness, because the Spirit is truth. For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one. And there are three that bear witness on earth: the Spirit, the water, and the blood; and these three agree as one.
There is but one God, but He exists eternally in three Persons. Divine Majesty! Divine Mystery!
The Holy Spirit has been given to us who believe as a witness. Our baptism should serve as a witness to the saving grace of God. And the blood of Jesus Christ, shed for us, should also serve as a powerful witness that we who believe belong to Him—forever.
