2 Peter 1:3-9
"3His divine power has given us everything we need for a godly life through our knowledge of him who called us by his own glory and goodness. 4Through these he has given us his very great and precious promises, so that through them you may participate in the divine nature, having escaped the corruption in the world caused by evil desires. 5For this very reason, make every effort to add to your faith goodness; and to goodness, knowledge; 6and to knowledge, self-control; and to self-control, perseverance; and to perseverance, godliness; 7and to godliness, mutual affection; and to mutual affection, love. 8For if you possess these qualities in increasing measure, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ. 9But whoever does not have them is nearsighted and blind, forgetting that they have been cleansed from their past sins."
I'm a big fan of principle over particular. If we know the principles of something then the specifics of that things are easier to recall and apply. Knowing that love is patient, kind, and forbearing is an easy list to memorize but becoming a person who is by disposition patient, kind, and forbearing feeds on itself and begets more of the same. We're even more empowered when we realize "love" is simply a word we use to describe value.
I value you. I value this person so much that I will be patient and kind, hopeful and trusting with the, I do so because I value them as more significant even more than myself (Php. 2:3).
I think one of the best ways of developing this disposition is the practice of "spiritual disciplines." There are several good books on the topic. Richard Foster's "
Celebration of Discipline" is a classic. If you like the Quaker approach to spiritual disciplines you'll enjoy Foster's book. A more evangelical tome is Donald Whitney's "
Spiritual Disciplines for the Christian Life." It's a little more concrete than Foster's book. Since you're a woman you might consider Barbra Hughes' "
Disciplines of a Godly Woman," although it is written for married women. She may have a volume written for the younge woman. If you're interested in something more theological then "
Knowing God" by J. I. Packer is a must read. I've read all these books more than once and highly recommend them. For the men reading this post R. Kent Hughes' book, "
Disciplines for the Godly Man" is also highly recommended.
Something else I'd like you to consider:
if you're not out and about acting like the world then you're already godly whether you feel it or not.
