Get your own hearts into a humble frame; and abhor all the motions of pride and self-exaltation. A humble man has no high expectations of another; and therefore, is easily pleased or quieted...He is content that others go before him; he is not offended when others are preferred. A low mind is pleased with a low condition...But pride is the gunpowder of the mind...A proud man's opinion must always go for truth, his will must be a law to others, and to be slighted or crossed to him seems like an insufferable wrong".

If you don't think much of yourself, you're not offended when others overlook you. Because, after all, who are you to be singled out for special notice? If you don't think much of your mind, you're not horrified when others disagree with you. If you don't think you're always right, you don't resent others doing things their own way.

This is nothing but pride.
Believers often mistake their own pride with a zeal for God. It's not their own opinions they insist on—but God's Truth! It's not their way they want—but God's way. And so on.

How do you tell the difference? How do you know you're contending for God instead of yourself? I don't know the full answer to that. But this much I know:
1.Your zeal is not godly when you feel contempt for others. When you look down on them or gossip against their ignorance or folly, the Lord is not in your zeal. Godly zeal is always mixed with love, sympathy, and pity for people in the wrong.

a.For proof, see James 3:13-18; Matthew 23:37-39.

Nothing prevents peace more or destroys it faster than pride. "By pride comes only contention" (Proverbs 13:10a). If you want peace, humble yourself.
