One thing which seems to be deeply lacking in much of modern evangelicalism is the study of God's attributes. I believe if more of us set aside serious time to study God and His perfections we would not only know him better but it would cause us to worship God in awe - and it would change our lives. Below we have a short description of God from the Westminster Confession of Faith with links to more in-depth studies in most of the attributes it lists. Then, below that I have posted many free resources like eBooks and lecture series' on God and His attributes. Lastly I have selected a few books for purchase in case you want to even go deeper.
Of God, and of the Holy Trinity
I. There is but one only, living, and true God, who is infinite in being and perfection, a most pure spirit, invisible, without body, parts, or passions; immutable, immense, eternal, incomprehensible, almighty, most wise, most holy, most free, most absolute; working all things according to the counsel of His own immutable and most righteous will, for His own glory; most loving, gracious, merciful, long-suffering, abundant in goodness and truth, forgiving iniquity, transgression, and sin; the rewarder of them that diligently seek Him; and withal, most just, and terrible in His judgments, hating all sin, and who will by no means clear the guilty.
II. God hath all life, glory, goodness, blessedness, in and of himself; and is alone in and unto himself all-sufficient, not standing in need of any creatures which he hath made, nor deriving any glory from them, but only manifesting his own glory in, by, unto, and upon them; he is the alone foundation of all being, of whom, through whom, and to whom, are all things; and hath most sovereign dominion over them, to do by them, for them, or upon them, whatsoever himself pleaseth. In his sight all things are open and manifest; his knowledge is infinite, infallible, and independent upon the creature; so as nothing is to him contingent or uncertain. He is most holy in all his counsels, in all his works, and in all his commands. To him is due from angels and men, and every other creature, whatsoever worship, service, or obedience he is pleased to require of them.
III. In the unity of the Godhead there be three Persons of one substance, power, and eternity: God the Father, God the Son, and God the Holy Ghost. The Father is of none, neither begotten nor proceeding; the Son is eternall begotten of the Father; the Holy Ghost eternally proceeding from the Father and the Son.
