So I goggled "humble yourself" and discovered "Twelve Ways to Humble Yourself" by Janet Chismar on the Billy Graham Evangelistic Association. I've linked it if you'd like to take a look.
But most helpful were several verses of scripture that had a transformational impact on my heart:
“Humble yourselves therefore beneath the mighty hand of God, so that at the right time He may set you on high” 1 Peter 5:6 Weymouth N.T.
“Humble yourselves before the Lord, and He will lift you up” James 4:10 NIV.
"And it will be said, 'Build up, build up, prepare the way, remove every obstacle out of the way of My people.' For thus says the high and exalted One Who lives forever, whose name is Holy, 'I dwell on a high and holy place, and also with the contrite and lowly of spirit in order to revive the spirit of the lowly and to revive the heart of the contrite'" Isaiah 57:14-15 NASB.
I also ran across several quotations that I inserted in the "Quotes of the Week" on the right side of my blog below.
"A man can counterfeit love, he can counterfeit faith, he can counterfeit hope and all the other graces, but it is very difficult to counterfeit humility." - D. L. Moody
"Grant, O Lord, that I may look for nothing, claim nothing; and that I may go through all the scenes of life, not seeking my own glory, but looking wholly unto you, and acting wholly for you." - John Wesley
