Who is God?What are the essential truths to know about an infinite God?  What are is irreducible minimum about God?  To know and worship God truly, we must acknowledge at least three truths about Him.

First, He is a triune God.  He is one in essence and three in person and the three persons (they are not manifestations or modes) are distinct in relationships and equal in authority (1 Pt. 1:2).  “There is only one and true God, but in the unity of the Godhead there are three co-eternal and coequal Persons, the same in substance but distinct in subsistence” (B. B. Warfield).

So, as the Father is not the Son and the Son is not the Holy Spirit, and yet the Father is in the Son and the Spirit is in the Father — all the members of the Trinity are in each other without being equal to the other members — and combined, the three distinct persons of the Trinity make up one God.  Further, the three members of this Tri-unity have distinct functions and roles, yet all serve to glorify the others and none is any less God than the others.

We tend not to think too much of the Trinity, yet the Trinity is essential because it establishes the uniqueness and transcendence of God, establishes the deity of all the members of the Trinity (which is important because the deity of the Son and Spirit are sometimes denied), and because it is intrinsically connected to the gospel and our spiritual life. Fred Sanders has noted, “Christian salvation comes from the Trinity, happens through the Trinity, and brings us home to the Trinity.…The more we explore and understand the depths of God’s commitment to salvation, the more we have to come to grips with the triunity of the one God.  The deeper we dig into the gospel, the deeper we go into the mystery of the Trinity.” [The Deep Things of God]

Secondly, we can only comprehend the character of God as we contemplate His attributes as they are revealed in Scripture.  These attributes can be divided into two broad categories — communicable and incommunicable attributes — demonstrating both His transcendence and approachability.  Here is a compilation of some of the most basic of His attributes:

Finally, because God is God, all life terminates on Him.  Life is not about us; we’re not ultimate.  He is.  We live for Him, to please Him, and to glorify (reveal) Him (2 Cor. 5:9; 1 Cor. 8:6; 10:31).   All life is therefore theocentric (God-centered) and not anthropocentric (man-centered).

In summary,

“What comes into our minds when we think about God is the most important thing about us.…For this reason the gravest question before the Church is always God Himself, and the most portentous fact about any man is not what he at a given time may say or do, but what he in his deep heart conceives God to be like.   We tend by a secret law of the soul to move toward our mental image of God.  This is true not only of the individual Christian, but of the company of Christians that composes the Church.  Always the most revealing thing about the Church is her idea of God, just as her most significant message is what she says about Him or leaves unsaid, for her silence is often more eloquent than her speech.” [Tozer, The Knowledge of the Holy]

SOME THOUGHTS ON THE ATTRIBUTES OF GODFirst, I'm not sure that "attributes" is the best possible word to describe the characteristics of God's being. Louis Berkhof argued that "perfections" might be a better term. The language of divine "attributes" suggests that it is we who attribute certain qualities to God. That leaves us wide open to Feurbach's allegation that theology is merely the projection of human thoughts concerning the divine. In  reality however,  theology is an attempt  to reflect on who and what God is according to his self-revelation in Holy Scripture. 

Second, the distinction between God's communicable and incommunicable attributes (or perfections) cannot be easily maintained. What might be regarded as communicable properties, such as love and truth are properly incommunicable in their totality. God is infinite and eternal love and truth and we are but finite creatures. On the other hand, some of the supposedly incommunicable attributes such as omnipresence are capable of communication when shorn of their infinite and eternal aspects. The omnipresent God communicated presence to his creation - time and space. 

Third, the divine perfections should not first of all be considered in terms of God's relationship to the created order. God is not omniscient primarily because he knows all about the world he planned and made. Rather it is that in his infinite knowledge God plumbs the depths of his own being, and his omniscience is expressed in the full and complete knowledge that each person of the Trinity has of himself, and the other persons of the Godhead. 

Fourth, the doctrine of the Trinity should not be tagged onto the end of a study of the  attributes of God, almost as an afterthought. God is not love first and foremost because he loves us, but because of the loving union and communion of Father, Son and Holy Spirit. Similarly, the divine omnipresence is not primarily to be defined in relation to the creation, that in his being God fills all things. Rather, it is that the persons of the Trinity dwell in the same  divine space, each indwelling the other in loving communicative action http://exiledpreacher.blogspot.com/2008/04/perichoresis.html

WHICH has this: Perichoresis in the Gospel According to John (Article) which has this “An Exposition of the Orthodox Faith (Book I)” found here: http://www.newadvent.org/fathers/33041.htm

Fifth, the divine perfections primarily concern who God is in himself in the splendour of his being and in the fullness of the intertrinitarian relations. But the study of what are traditionally called the attributes of God should not be abstracted from the drama of redemption. The one Lord God who is Father, Son and Holy Spirit disclosed his perfections in all their dazzling glory when Christ offered himself to God through the eternal Spirit to save us from sin, Hebrews 9:14, John 8:28, 12:32, 17:1-2, 4-5, 1 John 4:8-10. By the communicative action of the Triune Lord we have been incorporated in the theo-drama of redeeming grace. Prayerful reflection on the perfections of God will enable us to play our roles in the drama of redemption with greater faithfulness and authenticity. Knowing God better should move us to worship him more adoringly, serve him more sacrificially, and bear witness to the gospel with greater boldness and compassion, Daniel 11:32, Colossians 1:9-10.

Chapter 1. That the Deity is incomprehensible, and that we ought not to pry into and meddle with the things which have not been delivered to us by the holyProphets, and Apostles, and Evangelists.

No one has seen God at any time; the Only-begotten Son, which is in the bosom of the Father, He has declared Him. The Deity, therefore, is ineffable and incomprehensible. For no one knows the Father, save the Son, nor the Son, save the Father. Matthew   11:27 And the Holy Spirit, too, so knows the things of God as the spirit of the man knows the things that are in him. 1   Corinthians   2:11 Moreover, after the first and blessed nature no one, not of men only, but even of supramundane powers, and the Cherubim, I say, and Seraphim themselves, has ever known God, save he to whom He revealed Himself.

God, however, did not leave us in absolute ignorance. For the knowledge of God's existence has been implanted by Him in all by nature. This creation, too, and its maintenance, and its government, proclaim the majesty of the Divine nature. Wisdom   13:5 Moreover, by the Law and the Prophets in former times and afterwards by His Only-begotten Son, our Lord and God and Saviour Jesus Christ, He disclosed to us the knowledge of Himself as that was possible for us. All things, therefore, that have been delivered to us by Law and Prophets and Apostles and Evangelists we receive, and know, and honour , seeking for nothing beyond these. For God, being good, is the cause of all good, subject neither to envy nor to any passion. For envy is far removed from the Divine nature, which is both passionless and only good. As knowing all things, therefore, and providing for what is profitable for each, He revealed that which it was to our profit to know; but what we were unable to bear He kept secret. With these things let us be satisfied, and let us abide by them, not removing everlasting boundaries, nor overpassing the divine tradition Proverbs   22:28 .
