Sovereignty and Providence are abiding principles. Sovereignty relates to the source of all authority and power, and providence relates to the source of all necessary provision. Whoever, or whatever, is accorded sovereignty makes the rules and divides the spoils.
When people reject the sovereignty of God, and His beneficent providence, sovereignty and providence don't disappear. In the vacuum, the State assumes determining power and dispenses provision at its will.
The problem is that the State consists of fallible, fallen men who are easily corrupted with power, and who are limited by their humanity. In reality, the dispensing of favours by the State leads the recipients of those favours into slavery to the State -- ask anyone who has regularly to fill out welfare forms.
The God who created all things has revealed Himself to be the I AM; the self-existent One; God Almighty. As such, He knows how His creation works best, and so His law provides the limits within which a prosperous and fulfilled life can be lived.
When lived outside those limits, I found that all was against me. Now that I seek to live within those limits (in the power of the provision of God's Holy Spirit), I find that God's soverignty and providence are far wiser and more generous that anything offered by the State.
