God is not subject to the laws He establishes for us, in the same way I am not necessarily subject to the laws I establish for my children. If I establish that my three-year-old cannot touch the stove, or if I establish that my fourteen-year-old cannot drive the car, it doesn’t make sense to say that I am also subject to these laws or that these laws, because I’m not bound to obey them, are not in harmony with my character.

“But Christ was above law, He was the originator of the law, so there was no yoke upon Him” (1 SAT 108.2).

About destroying. If destroying was against God's principles, God couldn't in any way destroy anything, whether voluntarily or involuntarily (if it is possible for God to do something involuntarily).

I couldn't find your quote. Given her other comments on the subject, I would assume she was talking about the ceremonial law. I was speaking of the 10 Commandments, which is a transcipt of God's character. I don't know what point you're wishing to establish, nor how this point fits into our discussion. My point is that God will not act contrary to His law, because it is a transcript of His character, and God will not act contrary to His own character.

Regarding destruction, destruction does occur as the byproduct of God's doing good. For example, the light of the glory of God, which gives life to the righteous, slays the wicked. So we can say that God kills or destroys, as long as we understand what that means.

God can only do good, because He is good. All that needs to be known of God, or can be known of God, was revealed by His Son. So we know that God will never act any differently than Christ did. We also know that from the fact that Christ's mission was to reveal the Father, and that when we've seen Christ, we've seen the Father.

The quotes I cited made the point that God is not the destroyer; that's Satan. God is the restorer.

We are left with something which sounds like a contradiction, but it's really not, which is:
1)God destroys.
2)God is not the destroyer.

If we understand the principle that God presents Himself as doing that which He permits, we can accepts these two principles without a problem. OTOH, if we understand that God does actively destroy, by voluntarily directing His own power against the desired object, then I don't see how one can avoid the conclusion that God is the destroyer (or at least a destroyer, in conconjunction with Satan).
