If God has to follow his own Laws, wouldn't that mean that his power would be limited?
How do you figure that? It is the implementation of God's infinite wisdom and foreknowledge about how something will turn out, that allows him to act in ways that do the most good for the most people, for the long term. For a timeless being, the long term is eternity.
To solve the problems of the abuse of free will, we are permitted to see for ourselves where it takes us when it is used selfishly, with no regard for the free will of others affected by our actions. All the conflicts we see on earth are the result of man using his free will in the wrong way.
We have never had God's rulership over us. But the Bible describes what it will be like when 'God's kingdom comes' and 'his will is done on earth as it is in heaven'.......only those who want what God is offering on HIS terms, will be privileged to enjoy it. (Isa 9:1-9; 65:11-25)
There is no limit to Jehovah's power but all his qualities...justice, wisdom, patience etc, are tempered by love.
He is perfectly controlled and not limited in any way by time.
All will account to him...whether they believe in him or not. (Heb 4:13)
