The beauty of impassibility

James Dolezal:

God need not experience changes of relation in order to meaningfully relate Himself to His creatures. He need only ordain a change in the revelation of His unchanging being in accordance with His wisdom and the needs and requirements or the creature in time. In this way, it is not God who changes but rather the manifestations of God, which are perfectly suited to the needs and circumstances of His creatures - whether according to wrath or according to mercy - at any given moment of their lives. It seems audacious to conclude that this unique manner of God's care for His creatures is somehow impersonal and lacking vibrancy. Why must God be personal and related to others in the same way as finite persons are? Why must He undergo change in order for His love or opposition to sin to be regarded as genuine? Indeed, it would seem that the One who is unchanging, simple, and purely actual in all that He is - which is exactly what classical theism claims about God - is the One who is most profoundly vibrant and powerful in relating Himself to others. Such a God may appear strange and unlike us in many significant respects. Nevertheless, one thing is clear: classical theism is not in need of a replacement model, as all other models must fall short of the true confession of God's infinite fullness of being - the confession that all that is in God is God.
