Here are some good posts on overcoming sin and walking in holiness:

Jonathan Dodson has a three part series on overcoming sin:
Know Your Sin
Fight Your Sin
Trust Your Savior, Not Your Efforts

Kevin DeYoung offers an Anatomy of Holiness, looking at what holiness is as it relates to our bodies.

Finally, Trevin Wax offers a prayer for Grace To Love What God Commands.

Hope you have a great Lord’s Day growing in your love for God and His commands!
