No grace shines more brightly in a Christian than humility. Wherever self comes in it mars the beauty of the work we are doing. Seek to do your work noiselessly. Do not try to draw attention to yourself, to make men know that you did this beautiful thing. Be content to pour your rich life into other wasted, weary lives, and see them blessed and made more beautiful, and then hide away and let Christ have the honour. Work for God's eye, and even then do not think much about reward. Seek to be a blessing, and never think of self-advancement. Do not worry about credit for your work or about monuments; be content to do good in Christ's name.
Matthew 23:12: And whosoever shall exalt himself shall be abased; and he that shall humble himself shall be exalted. (KJV)
John 3:30: He must increase, but I must decrease. (KJV)
1 Peter 5:5-7 (also James 4:6 and 4:10): Likewise, ye younger, submit yourselves unto the elder. Yea, all of you be subject one to another, and be clothed with humility: for God resisteth the proud, and giveth grace to the humble. Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time: Casting all your care upon him; for he careth for you. (KJV)
Proverbs 18:12 (also Proverbs 16:18): Before destruction the heart of man is haughty, and before honour is humility. (KJV)
