TRIUNE

John.c.16.vs.13-15 "When the Spirit of truth comes He will guide you into all the truth for He will not speak on His own authority but whatever He hears He will speak and He will declare to you the things that are to come. He will glorify Me for He will take what is Mine and declare it unto you. All that the Father has is mine, therefore I said that He will take what is Mine and declare it unto you."

Nobody who wishes to be taken seriously as a student of God's word doubts the doctrine of the blessed Trinity, God is One yet He is Three in Persons, which of His blessed Persons would you like to dispense with, is it the Father and Creator? the Son and Redeemer of poor fallen man? or God the Holy Spirit? the life giver who breathes into us the breath of life when we are born anew, the Sanctifier and the Enabler.
What seems less well recognised is that man too, created in the image of the invisable God is, a triune or threefold being.
That man has a outward person in the body of his flesh is not disputed, that he has an inward person of the phsyche or soul can be easily proved, but there seems to be a great deal of debate about the third dimension of man's being which is his spirit and a considerable confusion about what is that which pertains to the soul of man and that which pertains to the spirit or whether or not the terms soul and spirit are not interchangeable so that when we are talking about either one or the other the same thing is meant thereby. In Hebrews.c.4.v.12. we read...For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul nd spirit, of joints and marrow and discerning the thoughts and intentions of the heart.
There really shouldn't be any ambiguity on the part of the believer about whether or not man has a spirit which is as distinct from the soul as the soul is from the body. That there is this confusion and inability to distinguish and discern between what is of the spirit of man and what is of the soul is cause of so many of the doubts and confusions christians have and the reason why false doctrines arise and on the personal level bad choices made and mistakes made, leading to so much sorrow and pain in the lives of God's precious people.
That the unbeliever should not be able to identify within him or herself the presence of a spirit is much more understandable for it is this part of our being which the bible says in Ephesians.c.2.v.1.is slain, dead in trespasses and sin and which when we come to God through the cross of His beloved Son turning away from our sins He brings back to newness of life by the impartation of The Blest Holy Spirit.
Now we suddenly become aware of His divine Person and Presence, His peace comes upon us, our hearts are filled to overflowing with joy and newness of life and we become as the scripture hath said complete in Him.
