Here are, 1. Grace and sin in their true colours. Grace reigning is a reverence of God, and gives honour to him who is infinitely great and high, and to whom all honour is due, than which what is more becoming or should be more pleasing to the rational creature? Sin reigning is no less than a contempt of God. In this, more than in any thing, sin appears exceedingly sinful, that it despises God, whom angels adore. Those that despise God's precepts, and will not be ruled by them, his promises, and will not accept of them, despise God himself and all his attributes. 2. Grace and sin in their true light. By this we may know a man that has grace, and the fear of God, reigning in him, he walks in his uprightness, he makes conscience of his actions, is faithful both to God and man, and every stop he makes, as well as every step he takes, is by rule; here is one that honours God. But, on the contrary, he that is perverse in his ways, that wilfully follows his own appetites and passions, that is unjust and dishonest and contradicts his profession in his conversation, however he may pretend to devotion, he is a wicked man, and will be reckoned with as a despiser of God himself.

See here, 1. A proud fool exposing himself. Where there is pride in the heart, and no wisdom in the head to suppress it, it commonly shows itself in the words: In the mouth there is pride, proud boasting, proud censuring, proud scorning, proud commanding and giving law; this is the rod, or branch, of pride; the word is used only here and Isa 11:1. It grows from that root of bitterness which is in the heart; it is a rod from that stem. The root must be plucked up, or we cannot conquer this branch, or it is meant of a smiting beating rod, a rod of pride which strikes others. The proud man with his tongue lays about him and deals blows at pleasure, but it will in the end be a rod to himself; the proud man shall come under an ignominious correction by the words of his own mouth, not cut as a soldier, but caned as a servant; and herein he will be beaten with his own rod, Psa 64:8. 2. A humble wise man saving himself and consulting his own good: The lips of the wise shall preserve them from doing that mischief to others which proud men do with their tongues, and from bringing that mischief on themselves which haughty scorners are often involved in.
