I don't think God is insulted by anything I've said. If he is, he will let me know for sure. If people are filled with His spirit, they do know more than those who refuse to be because the Holy Spirit guides them into all truth.
if God could get insulted He would be subject to passions, as we are.
But the Lord specifically mentions that we must not use His name in vain and warns that blaspheming against the Holy Spirit is unforgivable. Unfortunately, using His name in whatever form to 'prove' our point (i.e. "God told me so," or "the indwelling Spirit says so," etc.) is walking on think ice, as far as I am concerned.
