Like fish taken in a cruel net,
Like birds caught in a snare,
So the sons of men are snared in an evil time,
When it falls suddenly upon them. - Ecclesiastes 9:12
We never know what is around the corner. We are like fish swimming in a net filled sea. We are like birds in a field of snares. We never know where the nest trap might bet or even what it might look like.
This is why we believers are told to be sober and be vigilant because our adversary the devil walks about seeking whom he might devour. It is why we are told to walk circumspectly. Eve had no idea she was going to be caught out by Satan when she went for her stroll though the garden.
We can have the same problem. We don’t know what is there to catch us out. So we must be ever vigilant as we go from day to day so that we are not caught in the snare of the evil day.
