Does God Change?

Development of the Derivative

Psalms 11:3 NIV

When the foundations are being destroyed, what can the righteous do?

Psalms 107:1 NIV

Give thanks to the lord, for he is good; his love endures forever.

Psalms 118:1 NIV

Give thanks to the lord, for he is good; his love endures forever.

Psalms 117:2 NIV

For great is his love toward us, and the faithfulness of the lord endures forever. Praise the lord.

Lamentations 5:19 NIV

You, lord, reign forever; your throne endures from generation to generation.

Daniel 4:34 NIV

At the end of that time, I, Nebuchadnezzar, raised my eyes toward heaven, and my sanity was restored. Then I praised the Most High; I honored and glorified him who lives forever. His dominion is an eternal dominion; his kingdom endures from generation to generation.

To understand the concept of derivative, it can be helpful to begin with simple functions.  Linear functions, in particular, are very good ones with which to start because their rate of change is always constant (i.e., the slope of the line).  Constant functions also have a constant rate of change--the rate of change of any constant function is zero. 

So what is God's rate of change function with respect to time? Does he have volatile rate function, one which changes wildly with small increments of time? 

NO!  We are told that God is steadfast and endures forever.  His rate of change is zero--in righteousness, in renown, in love, in faithfulness, in his reign. What a comfort to us to know that God is constant, that He will always be the same from generation to generation, everlasting!
