He is not subject to change. It is an impossible act. God can never change; His character and nature is set on a consistency of good, love, holy, faithful.
If we had to change something to get to where we are now. That means our character must have been flawed prior to the change. We need change, and thrive off it. Something needing change cannot depend on change It needs stability to help change come about in a helpful manner. It’s uncertainties are too many, and unstable. Ironic yes.
How can we place our hope and trust in volatile and constantly fickle people such as ourselves.
We need the stable, always faithful, never giving up grace and love of God to be our foundation to all in life. God is the only unshifting ground we can stand on.
He is the only one who you can hold on to through the good, the bad, the ugly, and everything in-between.
