How do we lie to the Holy Spirit? Does this mean that the Holy Spirit is the third person in the Godhead? What does the "whole counsel of God" say?
The Father and the Son are two separate personalities, with the Father having pre-eminence. The Bible contains no evidence of a third person in the God family.
Jesus taught about the Holy Spirit's function to carry out God's work, including inspiring one to speak the words of God and to resist the power of Satan.
The apostle John has provided at least eight separate forms of witness, establishing the veracity of Jesus Christ's identity as God in the flesh.
