I workout daily with an online trainer. Something he constantly emphasizes is the need for a strong core. Having firm support from the transverse abdominal muscles keeps us balanced and even helps us to feel powerful, confident, and strong.
And the hand of the Lord was on Elijah; and he girded up his loins…1 Kings 18:46
When we read in the Bible of Elijah “girding his loins” it actually means he tightened his belt, but it sounds very much like a description of the sort of activity that might produce six-pack abs.
I’ve sometimes thought that Gird Your Loins would be a terrific name for a Christian exercise club where people would come to work out to Scripture and tone their bodies while building up their faith.
Being a Christian in today’s culture requires strength: moral strength, strength in Bible knowledge, and also physical strength so that we do not falter or grow weary in doing good.
When facing the battles between good and evil, we must tighten our belts. Strengthen our abs. Gird ourselves for the days ahead.
Therefore gird up the loins of your mind, be sober, and rest your hope fully upon the grace that is to be brought to you at the revelation of Jesus Christ1 Peter 1:13
