I am reading a book by Nancy Leigh DeMoss titled "Holiness." It has made such an impact on my life, I really think everyone should read it!
In the chapter, "The Face of Holiness," she writes about the struggles against sin that we go through when we pursue holiness in our lives. She quotes Hudson Taylor:
Is there no rescue? Must it be thus to the end--constant conflict and, instead of victory, too often defeat?"
He later received a letter from a fellow missionary, John McCarthy, that would change his life. Part of it read,
Abiding, not striving nor struggling; looking off unto Him; trusting Him for present power; trusting Him to subdue all inward corruption; resting in the love of an almighty Savior;...this is not new, and yet 'tis new to me. I feel as though the first dawning of a glorious day has risen upon me.
His yoke is easy and his burden is light!
Nancy later quotes Charles Spurgeon:
Though you have struggled in vain against your evil habits, though you have wrestled with them sternly, and resolved, and re-resolved, only to be defeated by your giant sins and your terrible passions, there is One who can conquer all your sins for you. There is One who is stronger than Hercules, who can strangle the Hydra of your lust, kill the lion of your passions, and cleanse the Augean stable of your evil nature by turning the great rivers of blood and water of His atoning sacrifice right through your soul. He can make and keep you pure within. Oh, look to Him!
Looking unto Him, not striving, is the key to becoming more like Him:
But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord.
2 Corinthians 3:18
