The document provides an overview of key theological concepts regarding the nature and attributes of God from the Westminster Confession of Faith. It discusses that God is one, unlimited being without passions or ability to change. God exists as three persons (Father, Son, and Holy Spirit) in one substance, as revealed in both Old and New Testaments. The attributes of God are described as either superlative and inseparable (such as being immense, eternal, and almighty) or moral and communicable in a limited sense to humanity (such as love, mercy).

6. The impassivity of God
• God’s inability to be changed or change in regard to his
emotions
• Tied to all his other perfections
• Especially is Immutability
• Though God is not devoid of what we know of emotions,
His emotions are not expressed in any “changing” fashion
• His wrath, love, mercy, goodness are expressed constantly and
without change
• He is wholly active in these things
• God’s love is not like our love
• Not simply a more fervent or steady love – like ours, only
better
• It is infinite, never changing (increasing or decreasing)
• It is exactly what we need
God has no passions

10. God does not change: OT witness
Exodus 34:5-7 The LORD descended in the cloud
and stood with him there, and proclaimed the
name of the LORD. 6 The LORD passed before him
and proclaimed, "The LORD, the LORD, a God
merciful and gracious, slow to anger, and
abounding in steadfast love and faithfulness, 7
keeping steadfast love for thousands, forgiving
iniquity and transgression and sin, but who will by
no means clear the guilty, visiting the iniquity of
the fathers on the children and the children's
children, to the third and the fourth generation."

12. God is different than us
• Consider God’s attributes: they are inseparable
• Immense. Psalm 139:7 Where shall I go from your Spirit? Or where
shall I flee from your presence?
• Eternal. No beginning, no end.
• Incomprehensible. Does this mean that it is impossible to know God?
We can know what God reveals – everything necessary for life in him.
• Almighty. There is nothing he cannot do. Power is unlimited
(omnipotent).
• Most wise. Omniscient – governed by perfection.
• Most holy
• Most free. To do what he wills. Psalm 135:6 Whatever the LORD
pleases, he does, in heaven and on earth, in the seas and all deeps.
• Most absolute. all else can cease to exist. He cannot cease to exist.
Everything derives from him!
God’s attributes are superlative and
inseparable

13. God’s attributes taken together
• Human correlation
• What in your life correlates to the list of
attributes from the beginning of paragraph 2.1
to the phrase “for His own glory”?
• Some of his attributes God does not share with
his creatures or his creation
• For his own glory
• When we “give” God glory, we do not add to his
glory, but only “ascribe” him glory he already
possesses (Ps 29)
God has glorious, incommunicable attributes

14. God’s communicable attributes

• To what things can we relate, and in what way?
• How are those attributes in us like God’s?
• How are they not like God’s?

15. God’s self-existence
• Doctrine of God’s aseity. God doesn’t need
us!
• We add nothing to God
• Glory, goodness, blessedness reside in God
• He manifests his own glory: in, by, unto,
and upon his creatures
• We are totally dependent upon God
• He is alone the fountain of all being
• We are subject to his sovereign will and plans—
whatever pleases him
God is totally self-existent and independent

16. Implications of God’s self-
existence
• Nothing can surprise God
• Can something be “certain” in an absolute
sense—unless every circumstance is
planned/ordained?
• Hebrews 4:13 And no creature is hidden from
his sight, but all are naked and exposed to the
eyes of him to whom we must give account.
• Why do we not live in terror of God?
• God is due all worship and obedience

Father nor the Spirit; the Spirit is not the Father nor the
Son
