Num_23:19
God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?
John 14:9
Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father?
I look at the Trinity as a whole, The Godhead, or the combination of all three together, the Corporate Being.
God the Father, God the Son, God the Holy Spirit, "The Godhead" or what we believe God to be when we Pray to GOD.
Jesus is the express image of God in that, He is God Incarnate, (In the Flesh)
("He that hath seen me, hath seen the Father")
Jesus also Demonstrated the Power of God, by the Holy Spirit (Which is the Holy Spirit) working through Him.
Whenever we envision each Person of the Trinity individually.
1) The Godhead, you envision all three, Father son, Spirit
2) God is understood to be The Father, but when I envision God as being Supreme, to me He is The Godhead.
3) Jesus, is God Incarnate, with the Demonstration of the Spirit, thus again all three are represented, being the Godhead.
4) We never see the Holy Spirit moving, or acting, Independently of the Other two Persons of the Trinity.
Therefore my comprehension of God is always of all three, you cannot separate one from the other.
If you have seen the Son, you have seen the Father, if you have experienced the Son you have experienced the Spirit, which is the Power of the Father.
