"Humility is crucial for Christians. We can only receive Christ through meekness and humility (Matt. 5:3, 18:3-4). Jesus humbled himself and was exalted by God (Phil. 2:8-9); therefore joy and power through humility is the very dynamic of the Christian life (Luke 14:11; 18:14; 1 Pet. 5:5).
The teaching seems simple and obvious. The problem is that it takes great humility to understand humility, and even more to resist the pride that comes so naturally with even a discussion of the subject.
We are on slippery ground because humility cannot be attained directly. Once we become aware of the poison of pride, we begin to notice it all around us. We hear it in the sarcastic, snarky voices in newspaper columns and weblogs. We see it in civic, cultural, and business leaders who never admit weakness or failure. We see it in our neighbors and some friends with their jealousy, self-pity, and boasting.
And so we vow not to talk or act like that. If we then notice 'a humble turn of mind' in ourselves, we immediately become smug - but that is pride in our humility. If we catch ourselves doing that we will be particularly impressed with how nuanced and subtle we have become. Humility is so shy. If you begin talking about it, it leaves. To even ask the question, 'Am I humble?' is to not be so. Examining your own heart, even for pride, often leads to being proud about your diligence and circumspection.
Christian humility is not thinking less of yourself; it is thinking of yourself less, as C.S. Lewis so memorably said. It is to be no longer always noticing yourself and how you are doing and how you are being treated. It is 'blessed self-forgetfulness.'
Humility is a byproduct of belief in the gospel of Christ. In the gospel, we have a confidence not based in our performance but in the love of God in Christ (Rom. 3:22-24). This frees us from having to always be looking at ourselves. Our sin was so great, nothing less than the death of Jesus could save us. He had to die for us. But his love for us was so great, Jesus was glad to die for us."
