"Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour."
"Walks about" means goes about as a course of life. The Devil’s course of life is to destroy the dynamics of every Christian life. He ranges far and wide in search of prey.
The Devil stalked Job,
"And the LORD said to Satan, ‘From where do you come?’ So Satan answered the LORD and said, ‘From going to and fro on the earth, and from walking back and forth on it’" (Job 1:7).
"And the LORD said to Satan, ‘From where do you come?’ So Satan answered the LORD and said, ‘From going to and fro on the earth, and from walking back and forth on it’" (Job 2:2).
The Devil’s range can reach into our lives.
The Devil uses stealth. He stalks every Christian. He is now on the loose. He is on the prowl looking to trap you in his devices. The Devil always seeks opportunities to undermine our Christian walk. He is constantly on the prowl. He is not omnipresent for he can only be in one place at a time. However, he has a massive infrastructure of emissaries (demons) who do his bidding. They seek to seduce every one of us.
The Devil says, "I am looking for the spiritually naive. I’m patrolling the earth for simple souls who think that I am not real." The idea that the Devil walks about in a red union suit, having a forked tail and cloven hoofs and carries a pitch fork is a religious fairy tale. He camouflages himself with this idea.
