A.W. Tozer on why it is better for us to change than to even want God to change (paragraph formatting and emphasis in bold are mine):
Much of our difficulty as seeking Christians stems from our unwillingness to take God as He is and adjust our lives accordingly.
We insist upon trying to modify Him and to bring Him nearer to our own image. The flesh whimpers against the rigor of God’s inexorable sentence and begs like Agag for a little mercy, a little indulgence of its carnal ways.
It is no use.
We can get a right start only by accepting God as He is and learning to love Him for what He is. As we go on to know Him better we shall find it a source of unspeakable joy that God is just what He is.
Some of the most rapturous moments we know will be those we spend in reverent admiration of the Godhead. In those holy moments the very thought of change in Him will be too painful to endure.
