The Thought Life
1 Pet 1:13 Wherefore gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ;
To gird up the loins, a man would reach between his legs and grab the back part of his robe at the ground. Then he would pull that up between his legs and tuck it into his girdle or belt. This allowed him to run or work without getting tangled up in his robe. Peter is saying here, that you need to prepare your mind for action. “You need to use your head” is the way it would be said today. Think action!
Be sober: is from nepho (nay’-fo) is to abstain from wine. This Greek verb be is aorist imperative tense. It calls for definite decision, to begin to do this now and don’t just try! Keep sober in spirit, also means to be self-controlled, watchful. Don’t ever surrender your hope in the promised salvation.
This revelation of Jesus Christ is talking about His second coming (rapture).
Col 3:2 Set your affection on things above, not on things on the earth.
Set: This Greek verb tense is present imperative; is a commitment to a long-term way of doing something. A command to keep on setting your affection. Make it a habit, part of your life style.
Affection: Gk. phroneo; to exercise the mind, i.e. entertain or have a sentiment or opinion; by implication to be (mentally) disposed in a certain direction. This word is translated “mind” in Philippians 3:19, where Paul is speaking of the lost, says, “Who mind earthly things.”
Col. 3:2 (NASB) Set your mind on the things above, not on the things that are on the earth.
I gird up the loins of my mind, by actively thinking on, and anticipating, the return of Jesus. During rough times, I realize a living hope and a sure salvation! I constantly set my mind on things above. I don’t waste my time thinking about earthly things.
