Keep your mind clear, and be alert. Your opponent the devil is prowling around like a roaring lion as he looks for someone to devour.
~1 Peter 5:8-9, GW~
There’s a difference between a clear mind and an empty mind. The first is to de-clutter one’s mind of unhelpful things, of hindrances and nuances; the latter is just empty, stagnant– a mind in plateau.
If I keep on resting, I might keep my guard down, and there the enemy can attack me. “An idle mind is the devil’s workshop.” So I must always do things to keep my mind working.
We can rest our mind from a hard day’s work, but we must not forget that the enemy is just around us, waiting for us to be “at ease” — a time for him to destroy us with his mind attacks. If we want rest, let us rest in God’s presence, where righteousness and grace reign.
Be firm in the faith and resist him, knowing that other believers throughout the world are going through the same kind of suffering. God, who shows you his kindness [grace] and who has called you through Christ Jesus to his eternal glory, will restore you, strengthen you, make you strong, and support you as you suffer for a little while. Power belongs to him forever. Amen. (vv. 9-11)
