10 For, “The one who desires life, to love and see good days, must keep his tongue from evil and his lips from speaking deceit. 11 He must turn away from evil and do good; He must seek peace and pursue it.
12 For the eyes of the Lord are toward the righteous, and His ears attend to their prayer, but the face of the Lord is against those who do evil.” 1 Peter 3:10-12

Everyone these days, especially baby boomers, are looking for ways to stay young. Someday they’ll be saying 80 is the new 70. The main route to healthy vibrant living is staying in the fitness culture for as long as you can. Regardless of age, this lifestyle requires self-discipline and hard work. Actually, it involves some pain too because the workouts need to be serious to get you anywhere. If you were advising someone on what you’ve got to do, you’d surely say you must carve out time, you must push yourself and you must be consistent, all involving self-discipline.

Here Peter offers similar spiritual advice for leading a holy lifestyle. You must tame your tongue. You must turn from evil. You must do good. And you must seek out and pursue peace. Here the goal is not a lower heart rate, or a new pant size, or bragging rights, but winning the Lord’s approval, and to stay on speaking terms.

This is really the type of “cross fitness” in which you should be engaged!
