Today's Scripture reading is Ephesians 5:14-17.
Verse 15, "See then that ye walk circumspectly."
The follower of Jesus Christ must determine to live every day with our heads up spiritually.  When someone walks circumspectly, they are keeping an eye on what is going around them.  They are walking diligently.  
The enemy has many ways to trip and trap us.  As we are aware of the snares of the enemy, we can walk the right way all the way.  We can avoid so much of what Satan has prepared by choosing to walk circumspectly.  Keep your head up!!
