Tigthen Up Your Thinking
1 Peter 1:13, 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 Christ. 14 as obedient children, not conforming yourselves to the former lusts, as in your ignorance.
Your loins is the pelvic region of your body. In ancient times “girding the loins” meant to gather up long garments and tighten them up around your hips and waist so that you could run, do battle, or do something productive.
Have you ever seen a young trying to run with his pants sagging? Have you ever had the experience of getting some loose garment caught on something? This shows the importance of girding your loins.
To “gird up the loins of your mind” is to put your mind and thinking in a position to be useful to the Spirit of God, and not to your flesh. To be sober is to take a serious attitude. Resting upon the grace of God means to rely upon the power of God so that we can live in obedience to Him and avoid the condition of reverting back to our old ways.
A renewed mind is a terrible thing to waste.
