Let your eyes look directly forward, and your gaze be straight before you. Ponder the path of your feet; then all your ways will be sure. Do not swerve to the right or to the left; turn your foot away from evil.
When I was in the Arab world last year, I met an underground blogger (pen name: Al Edwards) who said this:
“Jesus informs his disciple, Simon Peter, that Satan has demanded permission to sift him as wheat. In Job chapter 1, we see Satan complaining that God has built a hedge of protection around Job so that Satan can do nothing to harm Job. Satan has to ask permission from God to harm Peter and Job, and it was necessary for God to remove his hand of protection from them both so that Satan could afflict them.
“I think we can safely assume there are many such times that Satan demands to do likewise to us.”
