1) God is immutable, meaning he does not change and cannot act contrary to his nature, as supported by several Bible verses. 2) God is eternal, but eternity does not mean endless time, as an infinite number of moments is impossible. Eternity means God is timeless. 3) God is impassible, meaning he cannot undergo suffering or be affected by his creation. His feelings come from his eternal nature rather than outside influences. Several Bible verses support this. 4) God is infinite, meaning without boundaries or limits. Denying God's impassibility or infinity is unorthodox.

3. Immutability:
God does not change, furthermore, it is
impossible for Him to change, which is to say
that God cannot act contrary to His
immutable nature.

 1 Sam. 15:29
 Ps. 102:26-27, cf. Heb. 1:10-12
 Mal. 3:6
 Rom. 1:23
 Heb. 6:18; 13:8
 Titus 1:2
 James 1:17

5. Geisler says, pp. 93-94
“For traditional theism, eternality does not mean time
without beginning and endless time. An infinite number
of moments is impossible: If an infinite number of
moments occurred before today, then today would
never have come, since it is impossible to traverse an
infinite number of moments (yet the time up to today
has been traversed). There is no end of an infinite, but
today is the end of all previous moments. Today has
arrived; hence, an infinite number of moments could not
have occurred before today. Eternality means
nontemporality or timelessness.”

7. Other than the fallacious procedure of taking
anthropomorphism literally, there have been
no convincing arguments that nullify the
Scriptural or the theological arguments for
the immutability and the eternality of God.

8. ““God’s ImpassibilityGod’s Impassibility
and Infinity”and Infinity”

9. Impassibility:
God cannot undergo passion or suffering;
nothing in the created universe can make
God feel pain or inflict misery on Him. This
does not mean that God has no feelings, but
simply that His feeling are not the result of
actions imposed on Him by others. His
feeling flow from His eternal and
unchangeable nature.

 1 Chron. 29:14
 Job 22:2-3; 35:6-7
 Ps. 24:1; 50:10-12
 Isa. 40:13-14, 28
 Rom. 11:35-36

11. Infinity
Though negative in form, the word infinite
(not-finite) is a positive attribute of God. It
literally means that God is limitless in His
Being; He is without boundaries, a Being
beyond the limits of the created universe.

12.  Gen. 1:1
 1 Kings 8:27
 Ps. 147:5
 Job 11:7-9
 Isa. 6:1; 40:12; 55:8-9; 57:15; 66:1-2
 Rom. 11:33
 Col. 1:17

13. Geisler says (p. 134) that to deny the
impassibility or the infinity of God is
unorthodox. God is not pernicious and God
is not finite. If God were pernicious, He
would change from day to day depending
upon how He felt, or the mood He was in, or
whether or not someone “made” Him mad.
This cannot be because God is impassible
