He has showed you, O man, what is good; and what does the LORD require of you but to do justice, and to love kindness, and to walk humbly with your God? – Micah 6:8

Wherein, then, does this humility show itself? It ought to show itself in every act of life. I would not advise any of you to try to be humble, but to be humble. As to acting humbly, when a man forces himself to it, that is poor stuff. When a man talks a great deal about his humility, when he is very humble to everybody, he is generally a canting hypocrite. Humility must be in the heart, and then it will come out spontaneously as the outflow of life in every act that a man performs.

But now, specially, walk humbly with God when your graces are strong and vigorous, when there has been a very clear display of them, when you have been very patient, when you have been very bold, when you have been very prayerful, when the Scriptures have opened themselves up to you, when you have enjoyed a grand season of searching the Word, and especially when the Lord gives you success in His service, when there are more souls than usual brought to Christ, when God has made you a leader among His people, and has laid His hand upon you, and said, “Go in this thy might.” Then, “Walk humbly with thy God.” The devil will tell you when you have preached a good sermon; perhaps you will not have preached a good one when he tells you that you have, for he is a great liar; but you may go home wonderfully pleased with a sermon with which God is not pleased, and you may go home wonderfully humble about a sermon that God means to bless. But when there really does seem to be something that the evil one tempts you to glory in, then hear this word, “Walk humbly with thy God.” ~ C.H. Spurgeon
