so that the requirement of the law might be fully met in us who do not live by the standard set by our lower nature, but by the standard set by the Spirit.

For people who live by the standard set by their lower nature are usually thinking the things suggested by that nature, and people who live by the standard set by the Spirit are usually thinking the things suggested by the Spirit.

so that anyone who resists the authorities sets himself against what God has established, and those who set themselves against Him will get the penalty due them.
